Being that person providing a better method halfway through a process. A cave person standing on top of another to cave art the ceiling? Halfway through I go "...You know you coulda just grabbed the log from outside, leaned it against the wall and climbed it". Someone halfway through whittling a bowl? "Oh, yeah, I saw some coconuts on the beach they'd be perfect".

I have the great hobby of Looking At Random Things, but the bad habit of assuming everyone else saw those things too so they must be doing what they're doing for a reason lol. That all said I'm sure I'd be dead from dysentery within a week or smtg, they wouldn't have to suffer me long.

I would introduce them to scrumpy, then teach them to grow apples so we can make more.

looking like that...most likely not a Don Juan. so hunting and fishing, i could scare anything to death...

Clan rock stacker.

I'd be a good forager, gatherer and tracker. I have a knack for identifying plants and animals and spotting signs of their presence. I'm sure with a bit of training I could become decent at trapping too but I've never done that.

I'd also be good at art, be that cave wall painting or figurine sculpting/carving.

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

dying

Coal mining, I fucking love mining coal

You'd be a lot taller and probably also faster (maybe not stronger). You'd become a god-king in no time. Or be killed as a monster.

Engineering and chemistry. You know, sharpening knives/arrows and distilling seawater into salt for food preservation.

test plant on grug before eating

Hitting people with a cudgel

I feel like I could get flintknapping down pretty well.

Not being on the internet

I guess I could build a cart/waggon for easier transporting the dead animals the other guys hunted. Not sure if that would be much appreciated or if I just would be the weird guy again.

Maybe a plough would be more useful.

And building/improving shelter.

I could also make a fire after failing some time I suppose.

I want to say "crossfit".

Dying from a decease.

I'm reasonably good at surviving pregnancy and childbirth, and nursing. Think all my other skills are only useful after the agricultural revolution.

Digging holes with a shovel. I'm good at that.

Whittling. Drawing.

Meditation.

Counting and therefore distributing spoils fairly. I would become a well-loved chief and would probably get laid more than I currently do, although the hairy partners may not be of my liking.

Our ancestors measured time to keep track of the breeding seasons of their prey as to not exterminate the local populations... so most likely for that

I'd be the hairless monkey that stays up all night and talks to plants

Ironically, brute force. I would be great at hunting too!

I'm good with plants, I'm observant, I like stargazing, I'm a good de-escalator. I'd probably an elder and end up doing some type of weather forecasting.

Being dead
