Basically the title, you need to use the skills you have now and be a productive member of society.
I don’t mean go back and show the wheel or try invent germ theory etc.
For example I’m a mechanic i think I could go back to the late 1800s and still fix and repair engines and steam engines.
Maybe even take that knowledge further back and work on the first industrial machines in the late 1700s but that’s about it.


I’m pretty good at hunting and gathering. Back before my broken neck and back, I was super into wanting to buy some remote place in the Appalachians and pseudo homestead. I have messed with many of the required skills. I wanted a place in the mountains with a year round creek for a water wheel. Building a foundry and forge, along with a manual machine shop. I was into what I could do using junk from pick-a-part type junk yards. People often only think of parts for whatever low end car, but if you actually have a fundamental understanding of cars and the various technologies in different applications, a junk yard gives tremendous access to industrial technology for many types of machines and equipment. Junk yards are not setup for that kind of thing either. A little bit of flattery and flirting with a cashier goes a very long way when none of the collection of parts on your cart have legitimate prices on the menu.
Even with my disability now, I could probably survive in the wild by trapping game and some minor gardening if the population was low enough and I was in a decent location compared to where/when I live now I’m the era of the 50 year mortgage fuckwit dystopia.
I could potentially survive on fishing. Not for fish, I tried that once and sucked. But crabs are stupid. A few times gone for fun and can easily get a few in not very long. If I was having to survive I would probably make bigger/more nets or traps too.
I wonder about spear fishing, have seen a few pretty large fish in shallow water before around here depending on the tide, some were certainly possible to hit, even if you don’t hit every time that is a lot of food.
