6'1" 165, but 137 for most of my life, 36" shirt, extra long arms, good in trees.
Most of 40,000 years we were hunters, gathers, tool makers, I would expect size and skills to match.
I am a hunter, when the tribe meets, we will be hunters, gathers, tool makers, weavers, basket makers, musicians, story tellers, just as we were.
Tall hunters see farther, throw farther, survive better. Smaller people stay in camp, easy to feed, make things good, gather from bushes gives Og backache.
Sit and watch for hours, not move, he who moves first loses. See movement, watch where going, get there first, waiting, downwind, no thought, not there, then from nothing, full speed, knockdown, kill, eat liver, drag back to camp. Og mighty hunter, feed litte people, camp take care of Og?
