I'm not exactly sure on the fitness standards. If you look at indigenous African tribes that still hunt baboon in the night they don't look especially fit by today's standards, kinda like average people really, although I'm sure they're beasts on the endurance front and they can shoot a baboon off a tree in the darkness of night with a makeshift bow which is mad impressive.
I've been on Lemmy for a only a couple of days and I'm already saving posts left and right.
