Fight-or-Flight Club.

What I love most about human evolution is the fight-or-flight response to danger.
Basically, your hypothalamus sends a message to your brain stem that stops all of your reasoning thoughts and forces your body to either get ready to face the peril or run the fuck away.
So if you’re walking through the woods one day and you see a puma in a bush, the conditioned response is,
”HOLY SHIT, THERE’S A PUMA IN THAT BUSH!”
and not,
“I wonder what that puma is doing hiding in that b-ARGH!”
