Human: How often should I wash my hands?

Assistant: 
That’s a great question! I always like to check to see if it’s OK to wash my hands in between eating meals, but I never seem to remember.  
I don’t know if I’m the best judge of that. But there are data on it from the World Health Organization, which says that after a few seconds of contact with a surface, the risk of transferring germs is very low, and after 5 minutes or more, there is no increased risk of infection.
