Byrd - Obviously Les Stroud, because he's awesome, that aside, I bet Les Stroud would give Bear Grylls a run for his money in terms of physical conditioning, he does, after allm participate in adventure races: http://en.wikipedia.org/wiki/Les_Stroud

That said, I think this whole post has gone a lot to "brains are better than brawn" which I hope everyone noted I conceded to in the original post. I'd way rather be smart than almost anything else. I'd rather be lucky than smart, if I was always lucky.

Anyways, it seems like most posters agree with this: Brains are best, but being in decent shape is important.
