Vsauce seems like he is the type of person that has to stay busy or he gets bored very quickly.  

I can sit on a plane staring at the seat in front of me for 4 hours without any entertainment and be fine so I think I could beat his 72 hours.  If it was an island with some trees, rocks, shelter, and food supplies, 100% I could make it a year.  Small white box like this picture?  Week at most.

Agreed, I don’t think any influencer (who’s career revolves around attention and interaction) is a good benchmark for this. 

When I had covid I was in the house alone for around 2 weeks, I did very little as I was quite weak (hit me hard thanks to asthma) and honestly it didn’t really bother me. 

Going back to work afterwards all I heard was “it must be such a relief to see other people again”, it wasn’t. I honestly wish it was for longer.
