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.

Dying, mostly.

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

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.

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.

Time travel, evidently.

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.

Is that Marjorie Trailer Greene?

I’m pretty good at thinking outside the box and innovating, so I’d probably just die.

Dogs seem to like me so maybe I'd be one of the first to domesticate dogs. I'd probably just live with dogs.

Breeding

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

Whittling. Drawing.

Meditation.

Excel, it wouldn't be useful but I'd still be great at it.

Dying

Starvation.

I'm a natural at shooting a traditional bow.
I know every edible plant in my area, and some that get you high.
I can find north without a compass, day and night.
I can make a fire from things I can gather in the woods.
I know how to safely fell a tree, split logs and build a shelter with hand tools.
I know how to act around most predators and have experience handling a spear.

I think I'd do reasonably well.
Sometimes I wish I was born in the stone age. My ADHD is completely gone whenever I'm in the wild.

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

Or brain surgery.

Dying.

i'm a fairly deft hand at pottery. i'm also decent at fiber crafts. depends when and where during the stone age, of course, that's a pretty big expanse. if i'm really lucky, i'd be in one of the many cultures with special spiritual roles for trans folks. i've also got good rote memorization skills, so i can help with oral history.

I’d be the best at powershell. Unfortunately I wouldn’t live very long.

sucking dick

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