Another thing to think about is going crazy while heʻs stuck up there. Mental deterioration is a problem, especially when he is so close to death all the time. He has to make sure that he relaxes, takes time to unwind and entertain himself, which you see him do by watching episodes of Happy Days and listening to disco (though this might have done the opposite).

His continuous practice of making video logs and finding funny tidbits to keep the levity in a survival situation is going to prove important.
