have you seen "Man vs. Wild"? similar show, but the guys name is Bear Grills or something like that and he brings a camera crew along with him. He's a bit melo-dramatic, but entertaining none the less.
I think I could do it. My family and I were always outdoors, camping, hiking. I have had a Ranger course. when you are raised by a military father they make sure if anything you can survive on your own in any situation that you may find yourself in.
