I really enjoy it so far, but there’s one statement on the episode “Defend” that I can’t help but believe is false. It doesn’t help that I can’t corroborate the claim with any other source on the internet. The narrator claims a woman has adapted to surviving cold desert temperatures at night by shivering less and thus losing less body heat, but that’s not how shivering and body heat work. You shiver to regain body heat that was already lost. For this reason, I’m having trouble trusting the entire credibility of the documentary.
