It seems to me that if our evolutionary ancestors were lazy sacks of shit like we are nowadays, we’d be a lot better off.
You exercise to stay in shape and keep healthy, because humans evolved doing exercise (hunting and whatnot). If we had evolved on a couch, our bodies would be most adept at staying on couches because we would have evolved that way and we’d be a lot better off now.
Yeah, but imagine how crappy you’d feel after you exerted yourself at all. Also, we’d all have been eaten by sabre-tooth tigers thousands of years ago.
Also, have you no work to do today? Would you like some of mine?
Well, if everything followed suit, the sabre-tooth tigers would be equally lazy.
