Another One, Cats, and Run: What's a cool fact about the human body that a lot of people don't know? /r/AskReddit 5h alwaysclimbing5 self.AskReddit Selftext 348 (96%) 446 vault13rev 720 pts 5h (edit 4h) If we were an RPG character, our main stat would be endurance. We are, by animal standards, hellishly undying and unrelenting terrors, these Terminator-esque nightmares that just DO. NOT. STOP So ancestrally we are persistence hunters. That is, our main tactic for catching prey without fancy weapons was to just run them down, especially in our way-back home of the African desert. You can still see it, all over the human body. We are nearly hairless. This lack of insulation means better heat dissipation. We have a ton of sweat glands, next to other mammals. Again, heat dissipation. Another one is our two-legged gait - walking for us is technically just a series of controlled falls. We let gravity do half the work, and as a result use up fewer resources and generate less heat (quadrupeds, on the other hand, have to do more work with more legs). Imean, imagine being a more-or-less gazelle of half a million years ago. You're eating, doing your thing, when this predator arrives, so you run off. Now most predators, they'll only chase for a short distance and then call it a day (watch cats, for instance). But this one... here he is again. So you run. He returns. You run again. He returns. You're getting hot -you have to stop and pant to lose heat, but he just keeps jogging.. You run. He keeps coming. You're tired -you're fast, but not for very long, and this stretches your limits. Eventually you just lay there, exhausted and heat-stunned, and this ludicrous hairless monkey just jogs on over and kills you. That's our claws, our sharp teeth, even without our technology and tool-making. We simply don't stop. siriuszstar:Iā€™m scared
