This show lasts only an hour so I have very little time to fall into absolute dislike with one of their personalities. The few times we've tried watching Survivor, I fell into absolute hate with at least one of the people within an hour and ended up just wanting to scream at the TV.
On Naked and Afraid, when they're dropped off to their destination, they have to strip down to nothing, and they get to keep one thing for their trip. From what I see, men always bring machetes and women bring fire-starters. Then they have to last in their destination for 21 days. I don't see any big prizes at the end of the hour either. :-/
Fire-starters aren't how former-boy-scout hubs taught the boys and I though. But we learned pretty fast. There were a bunch of survivalist things in the old RV when we bought it, but youngest son took all of those things out of there. LOL I looked at most of it as a waste of space since there's no way on earth you'll get me to do that "roughing it" kind of camping.
Oh...and I've seen several people "tap out" already. Just got through watching one where the woman was the only one to ever survive the whole time alone after the man tapped out at 11 days.
