Yeah. Enduring all that and surviving seems a stretch. Just like hacking your own arm off with a pocket knife because your hand was stuck between two boulders and you were dying anyway, so what the heck. Ridiculous.

The Lewis and Clark expeditions consumed something like 10 pounds of meat per day PER PERSON. It would be very difficult to freeze to death with that protein and caloric intake. Men could walk around naked for a short time in dead winter and be enveloped by their own cloud of heated water vapor.

Back in the day a white guy's hands got submerged in frozen lake water so the Inuits grabbed the nearest dog, irregardless* of whose it was, killed it, slit it down the ventral axis and stuffed the white guy's hands in. That was a movie I saw once, I think.
