That's what makes the show so BAD, and potentially dangerous for viewers. He REPEATEDLY makes terrible, terrible decisions. Why go around a ice-cold river when you can jump off a cliff, hope it's deep enough, struggle to swim across, climb a sheer wall on the other side, and then hope you can find a hot spring or start a fire in time to avoid dying?
He makes this kind of decision all the time, and it gives people bad ideas, generally. I'd say, on average, 90% of the things he does are the opposite of what you should do in a survival situation. Plus, with the camera guy there to talk to, a few extra takes when things go wrong, slipping him food or a warmer place to stay... The show is crap!
