When I was your age, grandkids, we lived in caves, and we walked everywhere in the snow, uphill, both ways. Why, back in my day, Neolithic women had fashion sense (study from 2007), not like today. Neanderthals created tools just as good as the cro magnon's. Okay, maybe they weren't as creative in their tools, but good work, they did.
Ah, *spit* you kids these days are all weak, you don't get enough "dangerous" exercise, like chasing saber tooth cats around. Boy, those were the days.
