Honestly if I had my current level of knowledge, probably hygene. Teach them to make soap (animal fat and a source of base like ash), wash their hands, keep poop away from potable water sources, stuff like that.

Remember, it literally took until Victorian times to figure out that washing your hands prevents disease.

Also, math. Teach them how to do basic arithmetic, how to use a unit of measurement to figure out how big something is, stuff we'd learn in elementary school but weren't rigorously developed until the Ancient Greek age.

Mandatory I'd have died more than once, but I suspect I would have been good at mental things like tracking and storytelling. I'd probably suck at everything else, too.

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

Dying from allergies & asthma.

While still living, the tribe could deploy me as an animal detector: place me at the front of hunting parties, and the moment I start sneezing & wheezing, they know they've got prey nearby.

I would excel in the use of the internet and computers as I would be the only one with knowledge about it. I would also be the only one who knows how to drive a car.

Computers! Shit.

Dying, mostly.

Navigation and being the first to try a cool looking mushroom and findout how dead I get.

I think excel would be good software for managing hunter rotations, supplies and stone inventory.

Oh! I'm actually somewhat decent with some useful things. I got sent to a wilderness school for fuck up kids when I was a teen. So I know how to, and have applied a lot of survival stuff.

I know how to effectively make a somewhat permanent shelter. I can make and use a bow drill to make fire, and along the same principal but with much more effort and time I could make fire with hand drill or fire plough techniques. I know how to make basic traps. I can make cordage, and have very, very very basic tracking skills. I know some edible and toxic plants in my area (not exhaustive by any means). I know how to clean and dress game. There's a lot of other stuff, but those popped into my head immediately.

It's been a long time since I've done all this, but the knowledge and know-how is all there. I'd actually be a decent person to have around!

Probably dying at age <1.

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.

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.

Time travel, evidently.

Breeding

Is that Marjorie Trailer Greene?

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

Whittling. Drawing.

Meditation.
