Hi, I'm Zi Yan and I am a lecturer at UCL Medical Physics and Biomedical Engineering and my research focuses on MR-guided surgical robotics. My mother is a doctor. As far as I can remember, she was always very busy and tired. As a trial, I always imagined that a robot would help her with all her work so that she could spend more time with me. This little fantasy was like a seed that eventually led me into the field of medical robotics. Richard Feynman is the physicist I admire most. I admire his passion for research and exuberant curiosity. The most exciting thing about medical physics is to investigate and see how scientific and technology advancement is changing people's life.


When I returned to Dragon Ball The Breakers recently, I realized that I still think this game is a lot of fun. Sadly, me thinking it's fun is definitely not going to make Season 2 undelayed. But that's actually what made me realize that if the developers aren't going to add new content for this game, maybe we should just add it ourselves. So I decided to create a ton of new rule sets for the game, put them all on a wheel, spin it, and play whichever one comes out. Will it change the game enough to be fresh? The only way to find out is to spin that wheel. Let's go ahead and see what we're going to be playing Dragon Ball The Breakers with now. Up first, it's on the way! Yeah! I wanted to play the dodgeball one. Alright, so first, okay, so for dodgeball, we're all going to go to one cave, and then the raider is going to stand outside and fire projectiles into the cave. Last survivor standing wins dodgeball. Alright, here we are gentlemen, we've got the dodgeball game. Looking good, looking good, then we have our raider here. The only problem is our heart's going to be beating out of our chest, but I think that's fine. Back up a little bit, like right here outside of the thing, that way we have a clear line. There we go, there we go. Alright, everybody back up. Once the timer in game hits 13 minutes, you can feel free to begin dodgeball. I'm giving 13 minutes so everybody knows to get ready.  Obviously, momentary cover is fine. We'll work on the rules. Maybe there's an even better cave out there somewhere. Alright, 13 minutes in five, four, three, two, why is Mark getting all so close? Alright, go, go, go, it's dodgeball time!  Oh, dammit, he went in for a punch, that was a mistake, guys, back it up. Damn! Oh, somebody threw a triple lead down, that wasn't against the rules, I guess.  Oh, damn, I'm cracked! I'm cracked! I'm the dodgeball champ!  Yeah, just go ahead and put me down, I didn't... Wait, did I win? No shot! Yeah!  Oh, pretty good first game of dodgeball, do we want to do another dodgeball? Hold R3 to untransform? Oh, I completely forgot about that. Alright, everybody in the cave, everybody in the cave. I'm gonna go pretty far this time, chat. That's the... Ah! Who did this? Stop! Oh, God. Alright, everybody in the cave, we're gonna start at 11.30, and I'm gonna be zooming back and forth, I'm gonna catch you guys.  Three, two, one, stay over the blue phase, okay. I got somebody, ha ha! There we go, now that I'm not locked on, now we're getting the true spirit of dodgeball. Ha ha! Oh, somebody got hit in there, I see you hitting there, I'm gonna get you. Nah, don't even try to run. Oh, I got somebody again, let's go! Send supernova? If I don't get it in by 10 minutes, then I'll throw in supernova and that'll be considered I lost. They're fast, I'll give them that, they're just both going back, left, right. Oh, God, he keeps going back and forth, he doesn't have to do that, but I'm gonna... Snipe! Oh! Ha ha ha ha! He did a little fake out. He's good, I'll give him that. No, I have 10 seconds. How did that not hit him?  All right, here's your reward.  Damn, there was two of you left in there? Hey, you're gonna wanna leave this place, man. Frieza's gonna destroy this and use it for dodgeball.  At 10 minutes, as long as you're not locked on, you're free to fire. 10 minutes, 10 minutes, wait!  We have a new arena.  Kai! All right, 10 minutes go! 10 minutes left, it's dodgeball time. Keep your eyes on Frieza, that's my advice. I keep your eyes on Frieza. Is he going backwards? Is he getting closer? What is he doing? Damn! Hit him, not me, hit Tyler, not me! Hit Tyler, not me! Hit Tyler, not me! Well, I'm not winning this one. Damn, okay, well, Tyler won, Tyler won. I feel like the range would have been better, but that still works. I think that's a good finale for dodgeball. All right, well, I'm not gonna lie, I'll take one dodgeball win. One dodgeball win is enough for me. Now, let's go ahead and roll to see what version of Dragon Ball the Breakers we're going to be playing next. Let's see here, let's see. And we've got no shot. Prop on? All right, all right. Okay, so everybody feel free to, don't transform in front of me, but I'm going to leave. I'll come back when I'm fully evolved and I'll give you more time if possible. But as long as you stay within these city lines, no passing the fences, you have to stay within the white picket fence area. You can hide wherever you want. Good luck, I'll come find you when I'm a grown man and let Prop Hunt begin, go! Transform, go hide, hide, hide, go transform. I'll go take a walk. They think that this is such a beautiful place. I'll give you guys until 12 minutes, just so you really have time to really buckle down. Good evening. Do you think they should like and subscribe this video? Please help me. Later. All right. Let's see how well they've done at hiding the... All right, all right. I was just seeing, I thought maybe they were breaking the rules. I know somebody's going to be trying the mean street strategy. Oh, there's definitely somebody in here. I don't know what you can change into as well. Like, I know they're random, so not everybody's going to get to pick what they chose. There's got to be one in here, right?  This is too obvious. Oh, okay, dude. Which one of you is fake? This one looks smaller than the other two, by the way. Dude, give it up.  People got disconnected. What? Oh, two people got disconnected.  Okay, this is not natural. What? You're likely story, dude. Freeze! Freeze! Likely story.  All right, free. No. Really? Oh. Come on, man. Yeah, step outside, buddy. Step outside. Are you the only one in here? You seem to be the only one in here. All right, who's next? Where could people be hiding? Over here? Well, you got seen, man. You forgot the camouflage. Robusted out the club. Get off me. Damn, you destroyed the whole building for what? Shit, I brought camouflage, man. All right, two left. These guys are good at hiding.  Ha-ha. Who raised him? Somebody flexed and raised him. Yeah, why don't you go ahead and step outside for me? Ha-ha-ha. Okay, so whoever's left wins, I am impressed. Let me find him, let me find him. Don't leave your spot, I want to find you. Last option is key sense. Okay, I do want to, you know what? He's already won. Where is it? No shot. Where was he hiding? Ha-ha.  Congratulations. You played a mean game of prop hunt. You played a mean game of prop hunt. Get over here. Get over here. We're going to the next round. Hey. All right, line up in the city for the prop hunt games. I think we'll only do two rounds of prop hunt, so this is gonna be it. Whoa, it's Little Cell Jr. All right, so you can go ahead and head out. I think everybody's here. Two, three, four, five, six. Wait, maybe not. Oh, there they are. Kai, late as hell. Hey! I guess that's actually pretty smart. That's actually pretty smart, because now we don't have barriers. All right, go ahead, Cell. Yeah, get out of here. All right, let me see what I'm gonna turn into. Okay, so we're definitely gonna be looking for an office environment here. We definitely want to look for an office environment. Does anybody want to do a collab? Any collabsters? Oh, Rico, Rico, collab with me, collab with me. All right, right here, right here, right here. All right, 12.30 is gonna go. Shares outside, worst ever. No, no, no, no, no, no, no, no, no, no, no, no, no, no, no. We're not outside, we're a bench.  Uh-oh, oh, he's in the building, he's in the building. Oh, Kai, Kai, get out here, collab with us. Collab with us, Kai. He's on his way, boys, yeah! Collab, collab, collab. Clean it up, clean up the lineups, clean up the lineups. Clean up the lineups. Oh, damn. Ha-ha, works like a charm, baby. Like a glove, like a glove. I told you, I told you, I knew this would work.   No, come collab with us.  Oh, he gave him the slam, he's different, he's different. Collab, collab, collab, collab, collab. Collab, yeah, come back, collab, collab. Yeah, yeah. Bench boys, we didn't bench boys. They're gonna be looking, who did that? Oh, no!  Damn, I can't believe those two actually thought they could get away with that. Ha-ha, ha-ha, ha-ha, ha-ha, ha-ha. Genius, genius. Hey, you guys did great. I'm getting out of them. Wait, wait! All right, well, that was prompt, but that was a pretty fun round. All right, anyway, chat, let's spin the wheel. Let's see what next, chat. I feel like we got two really good ones. Let's go ahead and spin. See what else is new. Hive Mind, no shot. Okay, it's Hive Mind. Hive Mind again, just for, just to remind everybody, Hive Mind means that all the survivors are going to have to come together in one group and then we all have to move together the entire time. For the purpose of this one, I'm going to go ahead and say Hive Mind, Hive Mind. All right, here's our last person. All right, boys, obviously let's loot up. Does anybody need anything here? Just, and remember, we can play normally, just get all the stuff. Altogether, remember, we have to move as one unit. We have to accomplish tasks, but we have to move as one unit. Does anybody have any change? Change, change, no change. All right, we'll move on.  If we all get level one, maybe we can jump them. All right, let's go to the city. Let's go to the city, there's gotta be good stuff. Okay, fuck, he's in his second form, boys. If you're not at one, get all the power. If you're at one, don't do it. He's here, everybody back in, back inside. Careful, flash, careful, flash.   Hive Mind. Bam. Rope-fang fist. Guys, I missed. Hive Mind, roll out, run towards the Cellgames Arena.  Hive Mind, regroup, Hive Mind, regroup. Shit, we're out of time. Does anybody have a revive? No! The Hive Mind run is too hard. I don't think anybody could ever win with this. Lay them alone. If you're alive, follow Rico. If you're alive, follow Rico. Where'd basket dude go?  This mode is hard when it gets chaotic. When it gets chaotic, Hive Mind, the mode falls apart. All right, well, we have to regroup with everybody else, so let's go. I regroup on me, I'm not resonant until I see all of us. All right, so this is what remains of the Hive Mind. All right, now we can actually start completing objectives again. Any barrier recovery devices? No, okay, well, what power key did we get? I guess let's go try to get the power key slot in. If we can get one power key in, I'll consider that a win. Damn, the Hive Mind works together fast. Okay, now that basically just told the raider that all of us are here on the key, so we really need to leave. Actually, hide it here, hide it here, hide it here, hide it here, quick, quick. Don't break the boxes, I made a mistake.  Everybody transform, hide behind these boxes. They give him a little bit to run away. He probably thinks we made it out. All right, we're probably good.  Who went up the stairs, don't do that. Are we all together? Make sure we all got our ducks in a row. One, two, three, it looks like we're all here. Everybody made it, all right, good. I'm gonna throw down my trampoline and we're gonna jump to, we're going to area D. We're gonna try to find the D key, fellas. Let's go. Guys, he doesn't even know we're going to the D key, we're fine. Yes, I told you we'd succeed, guys. Hive Mind regroup, stay tight. Okay, they know he, everybody hide. Get in between these boxes, hurry, hurry. In the boxes, in the boxes, hurry, hurry. If he sees one, he sees us all. Oh no, they're fighting. All right, that means we all have to fight, fight, fight, fight, fight, fight. Oh, we're not winning this. We're not winning this, fellas. Keep fighting, keep fighting. Ah, my eyes, who did that? Sal, please.  Hive Mind, go. Nevermind, res me. Uh-oh. Leave him alone. Follow Kai, follow Kai, follow Kai. This is impossible, yes. This is going to be, this is an impossible challenge for the viewers, I think. Ah, that's a really hard challenge. I don't think that one's even possible. I'm gonna be honest. Hive Mind might be impossible. All right, chat. The last game mode is going to be one last roll and it's, ooh, no jumping. This is gonna be a tough one. All right, so we can't jump. Can we beat this without jumping? I actually don't know. Obviously we have jumping substitutes, but I don't know if that's gonna be good enough. I feel like I just jump all the time though. Maybe that's the reason I feel like this one's so devastating. Literally cannot go into water unless you like fly out or something, no. I would recommend everybody have a transformation on deck just in case. I'm glad I could walk over that. Oh my gosh, where is the power key? Power key, I guess I could grapple away. Shit, can we even get to that one? Does anybody have their grapple up? I can roll. Oh fuck, I have to wait 50 seconds. Zero, do you have your grapple cooled on? Nice.  Well, what is it? Is it something good? Oh, Sensu Beans, nice. I could take those if you want. Appreciate that. Ooh, we got the whole team working on this one. What was that? All right, you guys might wanna hide.  Though far not jumping has been too bad other than when he got stuck on the mushroom. Yeah, I don't think he's coming in here. Oh, yes. All right, well, I wish I could climb up this wall but I can't do that because that's jumping. Is this worth my one grapple cool down? I'm gonna say yes. Nice. What are we looking for? We still don't have any keys, huh? This is rough. He's here. Damn, Zero just died. I can't go save him. I need to find keys. Okay, damn, all Kai just broke his back on the ground. Okay, here's my plan. I go in, I feed him a Sensu Beans. It should be as easy as stealing candy from a baby. Oh, he's thinking a big shot now too. Should be easy. There you go, take a Sensu Beans. Get up and run. How many people do we have? We need the tiny baby time machines. I wanna live. I haven't jumped not once and I still feel like I'm in control. I still feel like I'm in control. Run, run Kai, but don't jump. Easy. Okay, where's the rest of these keys? There's one B and there's one in E. I'm gonna go to E. Uh oh. He saw me. He saw me. He saw me. Please. I didn't transform. Hi, Sal. I can't believe we lost the Sal. Chat, you know which one I wanna do? Can we do one more, but I choose it? Unless it lands on it right now. Nope. I wanna do top-down camera. Yes, yes. I only had to do two roles to get the one that I wanted. Top-down camera only. I wanna play this one. All right, we're doing one more. Top-down camera. So for the final challenge of the video, we are gonna go ahead and do top-down camera only. If you're wondering what that's gonna look like, we're gonna look like this. We're playing an entire game of Dragon Ball the Breakers. Kind of like it's a game of, I don't know, what's a top-down game like this? GTA? Yeah, he's like OG GTA. Put chat on video so they can smile. All right, chat, everybody, smile for the video. Look at all these people from the sub-a-thon. They're smiling. I'm recording this video live in front of them all. Hi, me. Top-down camera only. I'm interested in seeing if this is actually possible for me. This is not necessarily something I can enforce on a whole lot.  Okay, that's a rock. Okay. Is it chest? There we go. Okay, I got some gold.   All right, let me go in here. This cave feels endless. Is there no chest in here? I don't think there's a single chest in this cave. Frader's also doing this, right? I have no idea. I think I can't enforce that on anybody. I'm just enforcing it for me, I think. Here's the strap, by the way. If you're playing top-down camera mode, always have map open. Wait, how do I get out of the water with top-down camera? Oh, I have to turn around. I haven't found any power keys yet.  If I can just figure out where the chests are, I could maybe get this going. Oh, it's gotta be in here, right? Surely.  I think I made a huge mistake. I'm not gonna be able to get back up there unless I hit the craziest trick in my life. Okay, here's where, okay. So if I hit this trick, I'm a god. Oh! That was sick, but I have to go back down there anyway. How do we still not have area A's key?  The raider's making no progress, I assume he's doing the same. The raider actually probably has it worse than us. There's no way that any of us are making progress. It's gotta be the new one. It's gotta be the random people that connected that are playing good.  Okay, I need to find out where this is, okay. I can't believe I'm letting my team down. I still have not found this thing. Oh no, the raider's here. I can tell because my heart's beating. Definitely not because I can see them. How many are transforming right next to it? They're close. I think I hit pretty well. Okay, they're gone. They're gone, I can come back out. Sometimes you gotta do what you can to survive with top down.  Run, run, run, run, run! How the fuck, you knew it was me! Please mercy, mercy! Oh, my brother is lost. Damn, he's good. Oh, fellas, wait, how did I get here? Where am I? How did you guys get me out of the cave?  Okay, well, I guess I'm going to, well, it's good for running away, I guess. No ability is useful except for, what just killed me? Ha, ha, ha! If I could just get to the trampoline, I could hide myself. I covered myself up with my trampoline. At least I got a nice shaded place to die. Oh no! Appreciate it, guys, appreciate it. Okay, we made it to be, I actually know where I am now. Hold on, let me get my car. I know where we are, I know where we are. So the keys could be, I mean, anywhere, honestly. Oh, wait, they said it. Oh, nice. All right, I'm going to X then. We should be able, this should be the super time machine. This should be the big wall right before the super time machine. If I know the game, this should be it. Oh, this must be it. Oh, come off it, man! I had to be close.  If they pick me up, I'm going to just immediately get this time machine going. I'm standing with this guy because I assume it's safe on this side. Everybody else is fighting. Damn it. Ha ha, the camera angle debuff is too crazy. I don't even know how to dodge. All right, well, if he destroys the startup system, I mean, we lose now, but maybe either of these two can survive. Is he trying to get over there? Which one is he going for? They're both deciding where to go. Oh, the desert one. Only one of them is going to win then. Oh, never mind, he decided to go to the desert too. This must be the meta. Oh, you might want to, you might want to go. You might want to go, oh, they escaped. They dodged the supernova. That was sick. You're no match for me. Well, my camera was top down, Frieza. It's hardly fray. That frayer? It was hard. I embarrassed myself. This was bad. That was a lot of fun though, to be honest. I would play the game with more made up rules like that. You know what, Bandai? I'm going to say just go ahead, add some of these made up rules to breakers. I think the game, it could just really use the updates, to be honest.


Good morning Cristina, good morning. How are you today? Oh, I'm nervous. You're nervous? Why? I'm scared of the deep water. Okay, so right today we will try to see how comfortable you are swimming in the deep water and you're telling me you're a bit stressed about this experience but you know how to swim. You're just not feeling good in deep in deep hand. Yeah. Okay, so here is shallow. Let's maybe show me what you can do on the shallow first. The water is cold and slowly we'll go in the deeper hands.  Okay, okay. I try to relax. I have no idea what is your skill. Okay, how you feel? You okay? Can you swim longer than that or you're tired now? I can't. I just see the drop. Oh, the drop is right here? Yeah. Okay, so maybe you show me on this where you feel comfortable. Just one whole lap, but slowly, okay? All right, here we go. Okay, take your time. Okay, all right, no problem. Okay, just remember when you want to swim in the deep side, the water will be the same. Okay, basically it's just the pressure you put in yourself that makes a big difference, but now when you swim, you're slightly too deep on your body. You're not very horizontal, so you sink. Basically, your legs are sinking too much. Okay? And you swim, it doesn't seem you're very comfortable or relaxed, so it means you are spending a lot of energy for a short distance. And what you want is the opposite. You want to float more and you want to don't spend energy. You want to save your energy so you can swim one hour non-stop, for example. Here, if you swim like this, I think within five minutes, you have to stop. So try to go more slowly again. Remember to look deeper in the water so your body will float more and slow down. Slow down, no pressure, okay? All right, take your time. Okay, what's wrong? No, I saw the slope. Okay, so what I think for what is your freestyle at the moment? I don't have freestyle. I need no front crawl. I can do a bit of back crawl. Yeah, so what I'm calling freestyle is this front crawl you do now. I think it's not an effective front crawl, so there is also a way to swim. And we will not focus on the speed, we will focus on your capacity to just be comfortable, okay? Right, so have you seen on the video how we do the salt of tiger or breaststroke? You know how to do breaststroke? No, I've tried it once. Okay, show me what is about the breaststroke. If you cannot do it, then I will teach you what is the tiger. Okay, Christina, okay, no problem. Look, take the camera, you can visualize on me, you have a screen inside. So I want you to learn how to, instead of freestyle or breaststroke fast, just learn how to float underwater.   So basically, we just try to keep your head on the surface without touching the ground. See, I'm going very slowly. What's happening? For this to happen, I just paddle with my hands one by one, okay? My legs behind just slowly kick. It's not a fight, it's really like going super comfortable. You're gonna, yeah, yeah, look, slowly. Your hands, okay, the paddling you're doing now has to be alternate, left and right and left and right. Show me how you do it. Bigger, left and right.  Yeah, yeah, yeah, relax, relax. Look, stop, stop, stop. That's the way. So now relax more and go more slowly. What you want is to keep the traction, okay? Don't lose it. If you pull too fast, after you have nothing to pull anymore. So you keep pulling slowly, left. When the left is gone, the right starts to pull. So you always have a pulling to move forward, okay? Okay, slowly, slowly. All right, easy. Okay, now you breathe on the surface, stay on the surface and kick with your legs. Try to finish just that distance, okay? Just my legs. Yeah, just until the water. That's my habit. Head always goes on the water. You can put your head in the water, it's actually not. Okay, I see where we are. I'll put the camera on my head so I can help you with my hands. Okay, okay, there is two things. Point one, you got to relax more because you're really stressed and that doesn't help you. It makes things worse. Point two, wait, point two, your hands, alternate left and right one by one.  When you want to breathe, just look up with your hand. When you want to blow your bubbles, exhale five seconds, okay?  Easy, easy. Blow your bubbles when you feel possible. Slow down your hands, it's too fast. Slow down, slow down. That's right, that's better. Take your time. Easy. And blow bubbles. Okay, it's all right. It's okay. We're going to slow down these things. Is it all right? Yeah. Okay, so there's two things you're doing better. You're slowing down a bit with your hands. Okay, that's better than just before.    One, two, three, four, breathe.   All right, take your time. One, two, three, four, breathe. Take your time, take your time. One, two, three, four, breathe. Yeah, that's right, that's right. Two, three, four, breathe. That's very good. One, two, three, okay. All right, much better. How do you feel? Okay, you control these entire things.  Okay, don't spend too much energy. Much better. We do one more time. And when you feel I'm not holding you, is everything the same? Basically, if you keep going like this, you will swim on your own. If you start to panic, you will make it like you want to sink. If you stay relaxed, you will continue. Okay, so it's you. I will be here carrying you.  If I feel you are not comfortable, I grab you again. Okay, so I just give you more freedom. And keep the speed extremely slow. Breathe slowly. Breathe, breathe, breathe. Easy. How do you feel? Okay, now I want you to understand something. You can float in the water, even you don't move. If you do nothing, you're not sinking. Okay, take a big breath in your chest and be flat under water like a star. Look at the bottom and just do your bubble slowly. Okay, and I will grab you back. We do five seconds without moving. Perfect. Now, hold the hair in your chest.  Okay, try to relax more. If you too tense up, right, you become hard. You sink more. If you're more relaxed, you're more flexible, you will float easier. Less tension. How do you feel? So you see basically what's happening with your body? Yeah, you become like this. Some people different, right?  So because you have strong legs, you would sink from your legs. So you become like that. Yeah. When you swim, you still walk, you just need to kick slowly for your legs to go back on the surface. So what you're going to do is the same. You don't do anything with your hands, just open like this, and you slowly move your legs just to don't become like that, but to keep it up slowly. Yeah, it's like a star. Okay, listen, your legs don't open up, close your legs and just kick slowly. Okay, basically you do freestyle kicks slowly. Yeah, your hands can be forward or open as you prefer. This really doesn't make much difference. Yes, that's good. You see your flat, right? So I want your legs to do this without being tired, non-stop. That will make sure your body stay horizontal. Now what are we going to do with your hands? Instead of doing this, you're going to start to do walking underwater, like we just did before, like a tiger. So you just kick, kick, kick and walk underwater. What I want to see is you go slowly. I want to see your speed under control. No stress, no emotion of fear. Okay. Okay, stop. Listen, what you're doing now, the pulling is going up too high outside of water. So what's happening if you don't have good speed?  If your body is underwater, your body floats easier. It's like an iceberg, ice cube, you know? If you put the ice cube too high, when you let it go, you will sink. If you keep the ice cube in the water, it will stay at the same level. So basically, I want your body to be in the water and never outside. So keep your hands in the water. You walk with your whole body underwater. You don't do this outside. You just keep pulling underwater. Okay? That's good. Yeah, stop, stop, stop. Just for you to feel. That was good. Let's go back. This time your legs, remember on the surface, they are sinking a bit. So what's happening, you start like this and then step by step. So just keep your legs higher, but the pulling with your hands was good. So keep the pulling. All right, that's good. Okay, much better, more flat. Okay. You go faster without being tired. Why? You're flat, so it's easier to glide. Now, your legs are still too deep. You need to feel in your feet the splash on the surface. Do not have to be crazy. That's not important. What is important is your legs to be on the surface. So you are not here. It's too deep. You are here. You feel the little splash, splash, splash once in a while. Okay? One more time. That's it. That's it. Keep under control, the speed and the stress. That was good. Your splash once in a while is okay. Okay? Not crazy splash. That was good. But from the beginning, you took a while before it happens.  One, two, three. You can walk three times, then eventually you breathe up with your legs still on the surface. Wait, you forgot about your hands. What you are doing is back to your kind of freestyle. Makes you sink more. Okay? Just keep your hands in the water so far. Just walk in the water. Your arms never go outside the water. Two, three, four, five. Okay. It's all right. When you breathe, look forward. You have an idea where you go. Your eye gives you an information about the environment. Okay? So when you breathe on the side, that's when you swim freestyle. Yeah. When you don't know how to swim freestyle, it's better than you just look up.   Look down, go backwards. Okay? So we do the same, but you don't breathe looking left or right. You breathe looking forward slowly. Easy, easy, easy. Easy, easy. When you breathe, easy.  You can pull two, three times as long as you need.  Okay? So we do five second bubbles. Breathe on the surface, five second bubbles. That's good. Okay. That's all right. It's okay. That was okay, but you still want to turn on the side. Just forward. Breathe and look down again. That's good. The kick and the pull are good. The breathing you freaked out a bit. Just no panic. Just easy. It's exactly the same. Just chin up forward. No, no, no. It's very good to swim head underwater blowing bubbles. You keep that, but when you breathe, don't turn left or right. Just lift up and take your time. Okay. Let's go back. Stop. That was correct. Because it was correct, I want you to understand you can do it. All right? Now we do again. And what I do is I'm here. There is no drop between us. Okay? I want you to breathe here. Looking at me when you breathe, blow your bubbles and come and see me. We stop here. Okay? Take your time slowly. It's okay.  Okay? Go back again. We do again. That was good. The beginning was good. The first bubbles, the brief was good, but after you immediately freak out. I want you to go back underwater and repeat. Breathe. Easy. Okay. Look, you did a good breathe, but after you scared, breathe and repeat the bubbles slowly. It's a repetition between doing bubbles slowly, breathing and repeat. Doing bubbles slowly, repeat. Okay? Don't get scared by breathing more and more.


The Kraft Foods Company presents the Great Gilder Sleeves. It's the Great Gilder Sleeves starring Harold Perry, brought to you by the Kraft Foods Company, makers of Parquet Margarine and a complete line of famous quality food products. Now let's join the Great Gilder Sleeves. Yesterday they arrived in his mail greetings from the collector of internal revenue, together with his 1945 income tax blanks. Instead of tossing them in a drawer there to ripen till March 15th, as anyone normally would, he sat right down and figured them out. Maybe that's why Gilder Sleeves slept like a baby last night, and why he's the first man downstairs this morning. Well, where is everybody? All out up there! Yoo-hoo! Everybody up! Come on, all hands on deck! I just happened to be feeling good this morning, Birdie. Did my whole income tax last night? Well, I'm glad you're feeling good. Yes, sir. When I feel good, Birdie, I tend to get hungry. What's for breakfast? Mr. Gilder Sleeves, that's a fair question. What do you mean? Well, sir, the milkman didn't leave no eggs this morning. He didn't hardly leave no milk. He didn't hardly leave nothing. Gee! I told him I said, I don't know why you bother to come around here tall. What did he say? He said, cause I'm so beautiful. I told him if his egg was half as precious as his tall, he wouldn't get so many complaints, and that's a fact. Well, do the best you can, Birdie, because I've got big things to do today, big things to do, and it's going to take plenty of fuel. Hey, Mr. Gilder Sleeves. Gee, you're early. Early? Not at all. I've been up for hours. Oh, well, let me hang up your coat for you. Oh, thanks. You know what I did last night, Bessie? I made out my income tax. I sat up at 1 o'clock doing it. Got the whole thing done and out of the way, two months ahead of time. Why, that's wonderful. I've never heard of anybody. Wonderful nothing. It's only common sense, Bessie. That's the way everything should be handled. That's the way this department should be handled. That's the way it's going to be handled in 1946. Yes, sir.  Do it now. Bing, bing. Make decisions. Take action. Clear the desk. That'll be our watchword for 1946, Bessie. Clear the desk for action. Well, if you really mean it, Mr. Gilder Sleeves. Of course I mean it. That's the official New Year's Resolution of the Summerfield Water Department. And I want you to hold me to it, Bessie. See that I do it. I want you to be tough with me. Make me toe the line. Bing, bing. Yes, sir. Well... That's what secretaries are for. To relieve executives of such details is... Tending to business. Well, if you don't mind me bringing it up again, Mr. Gilder Sleeves. There's quite a lot of things in your desk that have been there. Well, some of them since summer. That's just what I'm talking about, Bessie. People come in here. What kind of impression are they going to get? Why, anybody think this department was being run by a nincompoop? Yes, sir. You don't have to agree with me, Bessie. I like a girl who has opinions of her own. One who isn't afraid to disagree with me. I'll try, Mr. Gilder Sleeves. Now, what's the next move here? What's to be done? You're the secretary, Bessie. Give me my orders. Well, as I keep saying, there's all those papers on your desk. And really, if we don't do something about them... Papers on my desk, you say? Well, let's get at them. That's the way we do things around here, Bessie. Bing, bing. Let's go into my office. Yes, sir. I just got to get a bigger desk. That's all. Well, let's pitch in here. What's first on the list? What have we here, Bessie? I'm afraid it's another calendar. Huh? Indestructible life insurance company. I'm already up to my ears in life insurance. Up to my ears in calendars, too. I don't know why it is. We go for a whole year and nobody sends us a calendar. And then, all of a sudden, everybody sends us calendars. Yeah. Say, Indestructible life insurance company, Hobie R. Watson, general agent, Somerfield. So that's what became a Hobie. Last I heard, he had the Plymouth agency. I could use a Plymouth, but I certainly don't need any life insurance. Well, let's get going. Why don't you grab something, Mr. Joe Visage? What's that? It just fell out of the calendar. Oh, just a booklet. Are you the man we're looking for? Would you like a job offering the following advantages? Start at the top. Rapid advancement. Unlimited opportunity. Fascinating work. Valuable contacts. No office hours. Be your own boss. Retirement at 50. Hmm, who wouldn't? If you're a young man with these qualifications, apply to Indestructible life insurance. Sssh, hooey. Let's get down to work here, Betsy. What's first? Well, here's a letter from a man who claims, well, maybe you better read it. Huh? Citizens' Committee for Better Water Service. Never heard of it, but I'm against it already. Crockmorton P. Giller-Sleeve, Esquire, Department of Public Water, Summerfield. Sir. Hmm, I don't like that, sir. On behalf of the Citizens' Committee for Better Water Service, representing over 250 taxpayers in Summerfield, we... Hmm... It's a lie. Betsy, take a letter. Take 250 letters. A busy day today. What's that? What is that, buddy? Leroy tells me it's jungle noises. Jungle noises? What's that? Come on, Ben! Come home! Here it is! Boy, not in the house. Put down that gun. Maybe we better charge some other time, huh? Maybe we better charge some other time. You'll never win a battle that way. Ben, I didn't know you were here, my boy. Well... I'm here. Well, good evening. What are you doing with the mop? Oh... Bandets. Well, boys will be boys. Leroy, I mean. You're staying to supper, I hope. Well, I... Of course he's staying to supper. Oh, fine. Well, seems to me I've been staying to supper a lot lately. Glad to have you, Ben. Glad to have you, yes, sir. Can I sit next to Bennett's supper? We'll see, my boy. I think someone else might have something to say about that. Eh, Marjorie? Leroy's been simply monopolizing Ben all afternoon. I have not. Ben and me were playing Carlson's Raiders. Weren't we, Ben? Yeah, we were playing Raiders. What? I only showed him the first two. You want me to show you? Not at this time, Leroy. I need his arm to hang up my coat. Okay. Be the sentry. For heaven's sake, make Leroy lay off, Ben. He's been after him like this all afternoon. No.  The mission had better be postponed for tonight, Colonel Carlson. Suppose you go up and wash your hands for dinner. Ah, but now... Don't argue with your superiors. Your present mission is to go upstairs and wash your hands. Do you have your orders? Or, eh... art? Yes, yes. Well, let's go in and sit down, shall we? The dinner's ready. Sit down, Ben. Sit down. Thank you, sir. Have a hard day at the office, unki? It's been a busy day. Got a lot done, though. Cleaned up all my back correspondence. Told off a lot of people and cleared my desk right down to the blotter. Yes, sir, it's been bing-bing all day long. And last night, I stayed up at one o'clock, finishing my income tax. Did I tell you that? Over and over. Unki's been a regular fireball the last couple of days, Ben. I don't know what's come over him. It's because I gave up vegetables. Heh-heh. Ah, it's a good feeling. Feeling that you've accomplished something doesn't come very often. What have you two been doing? Oh, we've just been fooling around, haven't we, Ben? Yeah. Just fooling around. No, that's all right if you've got time for it. What are you planning to do now that you're out of the Navy? Do? Yes, for a living. Oh, I don't know, Mr. Jilder Slave, I... I guess I don't know. Well, surely you must have given some thought to your future after all those years you were in the Navy. You must have had some plan. What was it? I guess it was just to get out of the Navy. But what were you going to do after that? Well, I guess I thought I'd take it easy a few weeks and then look around sort of. I don't know. That's no way to do it, Ben, if you'll pardon my saying so. It doesn't pay to drift, my boy. You want to get right in there, take the bull by the horn, strike while the iron is hot. No, Uncle Mort, don't rush, Ben. He's earned a rest and I think he should take it. I'm sorry, my dear, but I'm telling Ben this for his own good. Business is business, you know.  Dog eat dog? Competition, my boy. Reconversion just around the corner. Flat irons, refrigerators. This isn't war anymore, this is business. Men are coming back every day. You get to get right in there and start punching if you don't want to get left. Well, gosh, I... But Ben doesn't know what he wants to do yet. Can't wait for that. The important thing is to get started. A man has obligations, my dear. Now, Ben, if everything goes well, you'll have a wife one of these days and children to support. Loved ones to provide for. Let's talk about something else, shall we? And speaking of loved ones, Ben, did you ever think of going into insurance? Well, almost a gill or sleeve. I guess I never did. What in the world would Ben do in insurance? Sell it. What does anybody do with insurance? Gosh, Mr. Gildersleeve, I'm afraid I wouldn't be good at selling things. That's nonsense. Just a question of getting your foot in the door.  Uncle Morton, really? Insurance? I'm serious, my dear. I happen to know they're looking for young men like Ben. I'll tell you what you do, Ben. You get on to Hobie Watson's Indestructible Life and tell him I sent you. Well, Mr. Gildersleeve, I... Or better still, I'll write you a note. Well, that's awful nice of you, but... Don't thank me. Glad to do it, my boy. I'll always be happy to give a service man a lift. It's guilty, excuse me. Yes, Bertie? We got a duck for supper. You want a carb or you want me to rattle with it in the kitchen? Bring it on, Bertie. The duck doesn't live that I can't lick. Well, anybody else got any problems? I have Mr. Anthony tonight. Bing, bing. The great Gildersleeve will be back in a few moments. Do you mind if I barge in a few seconds, Mr. Lang? No, go right ahead. Well, the other day my wife asked me to pick up the groceries. As I went out the door, the last thing she said was, don't forget to pick up a pound of parquet. That doesn't surprise me because parquet margarine is a spread that's preferred by millions. Well, it happens that our food dealer was out of parquet, so I had to bring back something else. My wife didn't like it. Well, sometimes there isn't enough parquet to go around, but that's usually a temporary condition because Kraft is doing everything possible to keep dealers supplied with flavor-fresh parquet. Anyway, it was an interesting experience for me because it taught me that wives are pretty fussy about the spreads they serve to their families. Yes, that's right. Women all over the country have found that a sure way to satisfy family appetites is to serve parquet margarine, the spread that tastes so good on bread, toast, pancakes, and waffles. They know, too, that they can buy parquet margarine at just about half the price of costly spreads. So be sure to keep asking for delicious, economical parquet, P-A-R-K-A-Y, parquet margarine, made by Kraft. Now let's rejoin the great Gildersleeve, who has continued busy for several days. Thanks to his friendly efforts, Ben Waterford has been duly sworn as an agent of the Indestructible Life Insurance Company and has commenced to learn the art of selling policies. But while Ben studies the theory from a handbook, Gildersleeve is scurrying around town finding live prospects. We pick him up now, for instance, at Mr. Peavey's pharmacy. Oh, Mr. Gildersleeve, what can I do for you this afternoon? Not a blessed thing, Peavey, not a thing. Just stopped in to pass the time of day. Maybe you would be interested in a sale we're having. It's a special on men's perfumes. No, thank you. Lots of nice odors. Pleasant and at the same time quite masculine. Chief of Police took a bottle of this the other day. Makes him smell like new moon hay. Well, the chief can douse himself with essence of hay, if he wants to. I will stick to soap and water. Need any soap? Not at the moment. Peavey, do you realize there's going to be a lot of ex-servicemen around here pretty soon? Not up in here already. What about it? There'll be more, but here's the point. Excuse me, Mr. Gildersleeve, telephone. Peavey's pharmacy? Oh, yes, Mrs. Ebersole, how have you been? Oh, I've been well, thank you. She's been well. Well, as usual, that is. Peavey, I'm... What's that, Mrs. Ebersole? Oil? Baby oil. My goodness, I didn't even know you're... I mean, I... Well, we don't recommend it for salad. Anything else? I see. Well, say hello to Mr. Ebersole for me. Peavey. I'll tell her, Mrs. Ebersole, thank you. Good night. Peavey, you waste enough time every day to make a fortune. Just common courtesy, Mr. Gildersleeve. What I was saying about the servicemen coming back... Yeah? Well, the point is, do you understand your responsibility toward these men? I think so. Just what is it you're after, Mr. Gildersleeve? I'm not after anything, not for myself. But now you take Ben Waterford, for instance.   Are we going to let a young fellow like Ben save our country and then come back here and not be able to make a living? Sure, I hope not. But the fact is, Mr. Gildersleeve, I don't need anybody to help me here in the store. I couldn't... Oh, no, Peavey. I'm not asking you to give him a job. I've already got him one. Well, then, what shall we... Just listen a minute and I'll explain. The point is... Oh, Bert. Well, well, things are really rushing today. Peavey's pharmacy. They could snap me this time, will you, Peavey? And I'm Clotch. I'm sorry, Madam. Have you tried a hardware store? Have you tried a department store? A jewelry store, maybe. Tell her to try a hot shop. Have you tried a hot... A clock shop? Well, I'm sorry, Madam. I can't think of anything else except Beckman's drugstore. They have everything over there. Thank you for calling. Good day. Peavey, you don't know the first thing about running a business? I wouldn't say that. I thought you just came in here. Did it waste time, anyway? Well, I didn't. What I came in here for was to tell you that Ben Waterford is selling life insurance. Oh. Don't interrupt. He's selling life insurance and it's your duty as a citizen to give him a hearing. But, Mr. Jonathan... I gave him your name, Peavey. When he comes in, be patriotic. Because in times like... Don't you answer that. Let it ring. When Ben comes in, Peavey... Peavey's pharmacy. Oh, I give up. Goodbye, you money grubber. Sister, dear. Answer it with your Leroy. Play with me. Please, Leroy. I like that. Go on, Leroy. Answer the door. Oh, gosh. Leroy, take your homework and the study, please. Okay. See you later, Ben. Ben, sit down. How's the insurance going, my boy? Oh, I'm working pretty hard. That's the stuff. Did you see Mr. Peavey? Yes, sir. It's on this afternoon. Was he pleasant? Oh, yes, sir. He was very nice. I thought so. I went in there this morning and soft-soaked him. Of course, I'm a pretty important customer to Peavey. I get all my cigars there. I see. How big a policy did he buy? He didn't buy a policy. He didn't? Why not, for happen's sake? Well, he said he didn't want any. What'd you say? Nothing. I couldn't think of an answer to that. Ben, that's no way. You've got to force the sale. I'm afraid I'll never get the hang of it, Mr. Giller's leave. No, no, my boy. We mustn't be discouraged. When a man says he doesn't want any insurance, that's only the beginning. If you don't just give up, you stick around, make conversation, look for an opening. Well, I hung around for a while and made a little conversation. Oh, what happened? He saw me a bottle of perfume. That means you haven't sold anything yet in three days? No, sir. Not yet. That settles it. We're going to make a sale this evening. Right this evening. But Marge and I were... Marge, we will forgive you if you attend a business for an hour, so she'll respect you for it. But you can't sell insurance in the middle of the night. Nonsense. It's only $7.30. We'll go over and see Judge Hooker, sell him a policy, and you'll be back here by half past eight. But I don't think I know how to sell.  Oh, unexpected pleasure. Step right into the library and make yourselves comfortable. Thank you, Judge. Yeah, thanks. Care for a glass of K-lax water, either of you? I don't believe so. Ben? Oh, no, sir, I don't even drink beer. That's right. You know, Ben here is just out of the Navy. Yes, I understand you made a fine record. Excellent record. Is he any combat, Ben? No, sir. That's too bad. Well, I thought I was lucky. Oh, yes, yes. Well, how did you gentlemen happen to drop in on a lonesome old jurist this evening, if I may ask? Just find yourselves in the neighborhood? No, Mr. Gildersleeve thought I ought to... The fact is that Ben has a... Well, he has something he'd like to discuss with you. Well, I'm only too glad to do anything I can for a returning serviceman. Something legal, is it? Oh, it's perfectly legal. Ben misunderstood you, Horace. You see, although he's only been back in town a few days, he already has a job. Well, that's fine. Congratulations. Oh, thanks. Mr. Gildersleeve helped me get it. Good old Gildersleeve. People call him a blowhard, but his heart's in the right place, just saying. Good citizen, too. Thank you, Horace. What is it you're doing, Ben? Well, I'm supposed to sell life insurance. Oh. So that's it. Uh, Horace, I don't want you to think that, uh... That what? Well, I wouldn't want you to get a wrong impression about our little visit. Well, how could I possibly get a wrong impression? I assume that Ben here is here because he would like to sell me some life insurance. I sure would, Judge. Gildy, you could learn a lesson in frankness from our young friend here. If you didn't make such a habit of beating around the bush... I wasn't trying to cover up anything, Judge. I just didn't want Ben to start selling you a policy the minute we stepped in the door. That's no way. Well, suppose we let Ben sell it his way. Young man, do your worst. Thanks, Judge, and believe me, I'm the guy that can do it. Should I show him the folder now, Mr. Gillespie? Folder? Certainly. Okay. I got it here somewhere. Or at least I did have it. Maybe you left it in your other suit. Nope. Haven't got one. For heaven's sake, Ben, never mind the folder. Just tell the judge the gist of the thing. Oh, okay. Well, let's see.  And, uh... Shoot. She looks kind of sad. It's a nice picture. Now, don't try to describe the folder, Ben. Forget the folder. Just give the arguments why every man needs insurance. Oh, okay. Never mind Mr. Gillespie, Ben. He's never sold any insurance. You just go ahead and do it your own way. Okay. Well, the... the idea is that everybody ought to have insurance. Very good. Why? Well, for the... for the protection of his loved ones. Yes, yes. One never knows from which direction the sad blow may fall. A traffic accident, a sudden illness, an unexpected shock. Any of these might carry off the loving provider who's always seemed so strong and healthy. Are you in... Are you insured, Ben? No, what would I want it for? Ben, that's not the answer. Gildy, leave the boy alone. I'll see you here, Judge. We're not playing polar games. I'm interested in seeing Ben get a start in life. I want him to learn to do this thing right. Ben, they give you three main points, don't they? Yeah. Three main objectives. Now, what are they? Uh, get inside the door. No, never mind that. We're already in the door. Oh, well, and there's only two. Prove to the prospect he needs insurance and then prove he needs the kind you're selling. And get his deposit, he guards. Oh, yeah, that. That, yes. All right. Now, have you proved to the prospect he needs insurance? I guess so. I told him about the accidents and all. Let us consider that the need for insurance has been demonstrated. Continue. Well, the Indestructible puts out several policies. Here's the Ordinary Life Policy and there's a 20-payment combination of nudity and endowment and there's the Convertible Retroactive Policy with double indemnity. Just sell him Ordinary Life Policy and we'll be here all night. Well, the Ordinary Life Policy is just the Ordinary Policy. It provides maximum protection at minimum expense. The rates are low. Now, let's see. Starting at age... How old are you, Judge? Fifty-five. Oh, well, I got it right here in the table. Let's see. On a thousand-dollar policy, age 55... Who in the Dickens told you you could sell life insurance? Well, you did.  Anybody ought to be able to sell insurance. Insurance is a real need. Now, Judge, with a small down payment, you can buy your family the protection they deserve. I dare say the only thing is I haven't any family. You must have some. Well, I've got three distant cousins, all older than myself and all as rich as creases. But now, Mr. Gildersley, then, he's a family man. Of course. A niece and a nephew, the apples of his eye. You wouldn't want to have Leroy and Marjorie left without protection, would you, Gildy? I don't think you should, Mr. Gildersley. You stay out of this. You said yourself, Gildy, that... Well, there's no reason to do it now. I'm perfectly healthy. We never know from which direction the sad blow may fall. Got an application blank there, Ben? Sure, here. Oh, thank you. And don't forget, Ben, get his deposit. You old goat. Why don't I learn to mind my own business? Here from the great Gildersley again in just a moment. Your menu for breakfast may change from day to day because all of us like variety and foods. But whether you have toast, sweet rolls, pancakes or waffles, it's the spread that makes them taste extra good. I expect that's why millions of American families prefer parquet marjoram because on any breakfast menu or meal where hot bread...breads are served, parquet's fresh dairy-like flavor is still unmatched. It's the expert way that Kraft blends selected, refined vegetable oils and fresh pasteurized milk from the farmlands of America that makes parquet marjoram taste so good. And, of course, it adds important nourishment to your family's daily diet because it helps provide food energy and essential vitamin A. So for a quality spread, serve your family parquet. P-A-R-K-A-Y. Parquet marjoram. Made by Kraft. All right, my boy, come here and sit down a minute. I want to show you something your old uncle has done for you. Yeah. You see this? What is it? That, my boy, is a life insurance policy. It's worth $10,000. $5,000 to you, see, here's your name, and $5,000 to Marjorie. Now, what do you think of that? $5,000? Yes, sir, $5,000. Gee, that's swell, Uncle. When do I get it? Let us hope it won't be for a long, long time. Oh. Well, can I have a quarter now? No, now get out of here. Good night, everybody. The Great Gilder Sleeve is played by Harold Perry. It is written by John Whedon and Sam Moore. The music is by Jack Meakin. This is John Lang speaking for the Kraft Foods Company and inviting you to listen in again next week for the further adventures of The Great Gilder Sleeve. Ladies, why let meals get dull when it's so easy to liven up the flavor of foods with tangy, golden, Kraft salad mustard? You can blend this cream, smooth salad mustard right into cooked foods, spread it on sandwich meats for lip smacking flavor, or use Kraft salad mustard and gravies, relishes, and barbecue sauce for extra flavor zest. Also, be sure to try the sharper Kraft mustard with nippy horseradish added for frankfurters and sauces for fish. Get both kinds, Kraft salad mustard and Kraft horseradish mustard on your next shopping trip. NBC, The National Broadcasting...


Primary sclerosing cholangitis, PSC, is a chronic inflammatory condition of the bald ducts, which can lead to cirrhosis and liver failure if left untreated. Research has shown that gut microbiota may play a role in the development of this disease, but the exact cause remains unknown. In this study, researchers found that certain types of bacteria were more common in people with PSC than those without it. They also discovered that these bacteria could be used to develop a treatment for PSC. The researchers created a lytic phage cocktail that specifically targets one type of bacteria, called klepsilinumoni, which was found to be present in higher numbers in people with PSC. When given to mice with PSC, the phage cocktail reduced the amount of the bacterium in the animals' bodies and improved their health. This suggests that the phage cocktail could potentially be used as a treatment for PSC. This article was authored by Misotica Ichikawa, Nobuhiro Nocomoto, Sharon Credo Rousseau, and others.

Hello, in this lecture we will define petty cash. According to fundamental accounting principles, while 22nd edition, the definition of petty cash is small amount of cash in a fund to pay minor expenses, accounted for using an impressed system. When we think about petty cash, we're going to think about that small amount of cash we're going to keep on hand in order to spend for those miscellaneous items that we can spend cash for. We don't want the cash amount on hand to be too large because it is a liquid asset, has inherent risk, and therefore we don't want too much of it on hand at any given time. However, we do want a small amount on hand because it's convenient to pay for those miscellaneous items. Therefore, we're going to have a system where we have a set amount that's going to be the idea of this impressed amount. We're going to say this is the set amount we want and then we're always going to basically replenish the petty cash to get it back to whatever that set amount we decide to be is. So for example, we might decide that amount is $250, take some money out of our normal cash count, the checking accounts, and put it into our petty cash somewhere where we have it in a lockbox and we can then spend it for those miscellaneous items. At the end of a period, usually like a month or a week, we're going to go into that and we're going to take a look at how much is left in the petty cash versus how much we want in the petty cash amount. So remember that we always want, remember that we always want the $250 in the petty cash. We're going to count what is in petty cash and then we're going to replenish the petty cash for whatever we need to to get it back to that $250. Notice we don't need a journal entry in the petty cash amount because it already has the $250 in it. What we need to do is record all the expenses that have happened in order to get us back to that $250 amount. So what we're going to do is we're going to put the actual amount from the checking account back into the petty cash amount to get us back to this $250, then the difference will be whatever we spent the money on and hopefully we have all the receipts in the petty cash drawer that we're going to just add up. We're going to say, oh, there's a receipt for janitorial service for miscellaneous expenses for postage for advertising. We'll add all those up. The difference between what we need to get back to the $250 and what those receipts add up to, we will then post to something like an overshort account and that'll basically track what we haven't kept track of in terms of receipts in the petty cash. So we would have to take money out of the checking account and then not put it in the petty cash. It's already at the $250 where we want it, but we'll record all the related expenses related to those items that we expended money on for the time period.


And now I'd like to welcome our three contestants to name that fall! Mimi, Carl, and Theo The Throw Rugs. Here's your first question. Name one of the top five causes of falling. That would be loose rugs and carpets, Bob. That can't be right, Bob. Excellent answer, Mimi. Here's your second question. How can we avoid trips and falls in the bathroom? Add rugs to the floor, Bob. Oh, no. It's installed grab bars and slip resistant surfaces. All right, here's your third and final question. How can we keep floors and stairs safe? Get rid of trip hazards like rugs and clutter and use hand rails and lights on staircases. Don't fall for that, Bob. Oh, I'm sorry, Theo, but Carl is correct. Check your sources, Bob. And Theo, you be sure to check out cpsc.gov slash older adults for more information and safety tips. That's all the time we have. We'll see you next time on Name That Fall. So long, everybody.


What is environmental health science and why is it important? Imagine you have a caramel apple. Let's make it a peanut coated caramel apple. Now, imagine all the ways that apple might cause harm to someone. The peanuts, for instance, could trigger an allergic reaction. Sugar in the caramel could increase your chances of developing diabetes or heart disease. Are the preservatives and other additives in the coating safe? Does the apple contain traces of pesticides? And were the farmers and neighbors exposed to these pesticides as the apple was being grown? Then does the packaging the apple came in? Does it contain harmful chemicals? And did some of these get into the apple? Was anyone exposed to dangerous stuff while the packaging was being made? And for the paranoid, did the production of this caramel apple contribute to global warming? And as a result, increased the level of health risks around the world. On the flip side, though, this caramel apple is dripping with carbohydrates and proteins and vitamins and other nutrients that your body needs. And it's not just about you. People's livelihoods and as a result, their health could well depend on you eating that apple. So, should you eat the apple? Without some way of making sense of the speculation about the risks and benefits, the only thing you're likely to get is a headache. The good news is that there's help at hand. It's called environmental health science. By understanding the science behind how our environment affects our health, we can take some of the guesswork out of the decisions we make. This is incredibly important if you're procrastinating over biting into an egg-ticing caramel apple. But it also has some bearing on one or two other issues, like how can we develop safer products? How can we curb the rise of lifestyle diseases? Or how can we benefit from the gains of technological progress without suffering the pain of unintended health impacts? And as a bonus, the science of what happens at the intersection between our bodies and the environment we live in is pretty cool, although I could be biased on that front. Environmental health science, reducing risk and increasing benefits so everyone can lead a healthier life.


Good morning Hank, it's Wednesday. Come with me to speak at the United Nations. So Sarah and I first visited a picnic for TB survivors and activists and then attended a pre-meeting meeting and then the next day went to another pre-meeting meeting which you would think I'd find unbearable but actually I loved it because I love hating tuberculosis so much. Plus I got to see one of my heroes, Dr. Lucica Ditu and another one of my heroes, the writer and surgeon Dr. Atul Gwande and another one of my heroes, Dr. Salman Kashavji. For me being able to see these folks in real life is a little bit like how my daughter would feel about seeing both Olivia Rodrigo and Taylor Swift in the same night and then afterwards they were like, hey do you want to go out to dinner? And I was like uh yes and I got to hang out with them even more and tried to keep my cool so I didn't film that because I'm cool and I'm relaxed and I'm a normal person just like the world's leading TB fighters. The next morning it was time for the meeting itself which of course meant that it was also time for a fit check. Now I have a 40 minute walk to the United Nations which I'm going to spend just luxuriating in my anxiety. As I walked I thought about whether I'd have a chance to speak and what I would say and what an honor it is to represent not just Nerdfighteria and Partners in Health but also people who survived TB and those who didn't. So I made it to the grounds of the UN where there's this phenomenally beautiful landscaping that some of the richest people in the world get to look down upon which in my business is known as a metaphor and then I got inside where everything was for lack of a better term extraordinarily United Nations-y. This is cool. I got to wear the earpiece that does live translating and look at all the representatives from around the world and celebrate with other TB activists when the political declaration on tuberculosis was formally approved. Now the declaration includes big targets for reducing TB in the next few years which if honored will save millions of lives but of course it's only a piece of paper unless nations and their leaders fund and implement all the initiatives outlined in it. This was the second high level meeting on tuberculosis and I was thinking about how at the last one in 2018 Shreya Tripathi was still alive. Shreya was a teenager who sued her own government in India to secure access to the lifesaving medication Bedakwaleen for herself and others and she was also a fan of my book The Fault in Our Stars. Her fight took her to India's highest court where she eventually won but by then it was too late for her. Her lungs were simply too damaged for her to survive and so in the end her death was caused not just by tuberculosis but also by government bureaucracy and international indifference to TB. And so I was thinking about Shreya as the UN people told me that actually I would have a chance to speak as long as I kept it under two minutes. I wish I'd said more that this is a problem of resource allocation that disease does not treat people equally unless society treats people equally that we cannot go on promising to address this crisis without making the choices and sacrifices necessary to enact those promises. But here's what I did say. I want to begin by saying that 23 years ago Dr. Peter Mugeni in a room very much like this one said of HIV medications where are the drugs the drugs are where the disease is not and where is the disease the disease is where the drugs are not and that is the situation that we are in today with tuberculosis the cure is where the disease is not and the disease is where the cure is not. We have had a disease that is that is curable for 75 years that continues to kill 1.6 million people and it maybe it was possible to say in the 19th century the death from tuberculosis was caused by a bacterium called M tuberculosis but we can really no longer say that today we have to accept the reality that since we know how to kill that bacteria we know how to cure this disease. Today we have to accept the reality that death from tuberculosis is caused by human built systems by human choice. We have chosen the world that we share today and we can choose a better world. We are currently choosing a world where 1.6 million people die of tuberculosis and I believe that with your help together working over the next decade we will choose a world where no one dies of tuberculosis. Thank you. I hope I did okay and I hope that Shreya somehow knows that we are still fighting for her and will continue to do so until the fight is finished. Hank I'll see you tomorrow.
