i think you'd be better off trusting Russel coyte, then bear grylls...... if you don't know him, look him up on youtube.
hes the alter ego of australian comedian carl barron. hes quite funny.

I probably shouldn't divulge this, but here goes.  When I was in the army and a few years beyond I was president of The Fish Head Outdoorsmens' Club.  To be a member  you'd have to go fishing with the group and at some time during the outing promise to bite the head off of the next fish caught.  You'd pray it wasn't an eel or a big old catfish.  To move up in rank you'd have to bite the head off of something more challenging.  We were very young and not always very sober.  There was some serious competition and several really (I lack a word here) animals were beheaded.  My buddy Al was president for a while after he bit the head off of a newt.  I tried to blow him out of the water by doing an eel but it's skin was too though.  I got almost all the way through, but couldn't quite do it.  The slime was the worst part.  I eventually beat everyone and today remain president, if an inactive one, by biting the head off of a very large Blue Claw crab.  He was fresh out of the water and his claws weren't taped or anything.  I was just fast... snap.. done.  Somewhere there's a picture of me sitting there with the crab, a big bite mark out of him, his innards all over my face, and my poor buddy Gus, who knew nothing of the club, getting sick.  Today I'm very different... all life is precious and I'd never kill anything that I didn't have to.  I regret killing those animals. 
   I look at Man vs Wild not as a viable survival show.   You just won't pick up very many useful tips watching it.  But as ridiculous entertainment, it's sort of like The Fish Head Outdoorsmens' Club.  His camera man has to "share" everything that  Bear samples.  The show is weird, somewhat funny if you have that sort of sense of humor, and totally useless.

You're right, kid.. totally useless was a poor choice of words.  Mostly useless fits better I think.

anyone see Dual Survival?
I like the hippie... Cody something or other...

I'll have to look for it.  I very much enjoy good survival shows, even if they don't entertain us by drinking elephant poop water.  Did anyone see the episode where Bear climbs up the waterfall?  There he is, saying to the camera man how tough it is to make this climb and how he's fighting for his life, etc..  What the ((&^% are you doing climbing a waterfall in the first place?  I can think of no survival scenario where I'd climb a waterfall. None.  More nonsense.

Yea the rattler flavored urine sports drink was a bit much for me. I had to stop watching after that. All I could think when I watched that was..."Man I hope this guy gets paid a lot..."

I find Man vs. Wild pretty entertaining, but Survivorman less so. Neither of them teach practical survival skills. Here is a review of them both (which I think is a little harsh on Bear Grylls) from another site I frequent for bladesmithing inspiration: http://www.m4040.com/Survival/Survivorman.htm
