He hasn't taken a shower for over a week?
He needs sleep, it's surprising he hasn't started seeing things yet.
Anyway, for me. I'm sure ive gone over a week without a shower when I was like 5, but other than that, like 1-2 days.
Sleep was just 36 hours, never had a reason to stay up for days in a row and i dont think there is any reason anybody shouldnt be able to at least get a few hours at some point instead of being up for 5 days.
