one thing I've learned from Bear is if you're stuck in the desert you can piss on your shirt and wrap it around your head to cool down
And then the effects of ammonia on your skin turn your stomach and you barf, resulting in a huge loss of fluids...
I'm with the others on Les Stroud and Survivorman.
Bear ends up in a motorhome every night, with AC/heat and bikini girls feeding him grapes, while Les is out there dragging batteries around.
