Either making elaborate traps and contraptions out of sticks and stones.

Or brain surgery.

Dying

tool making most likely. also fire keeping, and cooking.

Finding fruit trees. Hunting would be my weak point.

Just by knowing how to wash my hands, medicine. Up until 20th century.

Fucking, for sure

Bronze peddler. “Hello, have you heard of bronze? Just attach it to your axe instead of stone. No more annoying stone chopping! And look, it’s shiny!”

Wanking

I wouldn’t survive long with my poor eyesight. Maybe I’d create tools or something. Love tinkering.

Sleeping and eating

Hitting people with a cudgel

I would invent God so others would do all the hunting and gathering for me while I partied in the cave basement drawing on the walls.

Knapping flint while fishing. And shitting under a tree. I feel like my ancestors have more in common than I thought.

Dying from a decease.
