There were no fat people back then, come on. There was nothing to make them fat. You can only get fat through taking in more calories than you burn. If you're running from dinosaurs and shit, saber tooth tigers and hunting mammoths it's a shame. Well, never know what they look like. Fucking all the time, according to Joe,. which is probably right. Like in the Andrithal, if we're going back to like our ancient brain, I would imagine it just wants fucking. Also like you. Maybe they had a mating time. We don't even know, you know? I doubt it.
