Another One, Cats, and Run: What's a cool fact about the human body
that a lot of people don't know?

If we were an RPG character, our main stat would be
We are, by animal standards, hellishly undying and unrelenting
terrors, these Terminator-esque nightmares that just DO. NOT.
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.
