ever seen the movie "into the wild"? it is the true story of a guy who did what you are talking about. he burned all his cash, gave away all his savings to charity and cut up all his identification documents. then he went into the alaskan wilderness and lived off the land kind of like the "depravation chamber" that you mentioned. anyway, the guy kept a journal throughout all of this and came to some great insights by completely abandoning everything like that to be all alone in the wilderness. it might be good for you to check it out. cheers, ryan
