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.

Selling camping gear

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.

Make booze

Dispensing elderly wisdom

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.

min-maxxing my sticks

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

Cave paintings, since I'm an artist! 😃 Also probably building tools and things since I enjoy building stuff in general

Being dead

Wololooo

I'm pretty ok at knapping flint and I'm not a terrible hunter. I'm also usually in poor health.

So I'd probably die as a baby.
