Seems like you guys aren't too sure about Bear. Here's some background info.

http://en.wikipedia.org/wiki/Bear_Grylls

You guys seem to have a misunderstanding of what Man vs. Wild is about. Bear's not trying to survive himself, he's showing you what to do in the worst possible situation if you were ever confronted with it. Yes, a lot of the stuff he does doesn't seem too smart, but when it's life or death you're faced with, you gotta do what you gotta do. Bear shows you how.
