Not that Savanna Idiocy is treatable much less curable but, there
wouldn't be marathons if this were typical behavior in humans.
It's BECAUSE such running is A-Typical that we have such
marathons!
But you know what is unquestionably typical?
Walking.
Running is an emergent trait. The physical abilities we evolved in
direct response to selective pressure ALSO lent themselves to
running.
In the aa world, all they could do is shuffle along
and would have been wiped by predators very quickly.
Birds are bipedal and can run on the ground quickly, but
the rest of the time they WALK.
Swimming and diving are Atypical.
Go look up: hunters and gatherers.
There is no equivalent for swimming and diving.
