They call it a double-sided economy.

I call it “let’s fuck everyone.”

Great question.

In culinary school there is an entire module on butchering - mammals, birds, fish, etc. I’ve always said my ability to cleanly and safely butcher all the things would make me very valuable in a post-apocalyptic scenario.

Creating and maintaining a fire isn’t easy but it also isn’t hard. Unrelated to culinary school, I’ve learned the skill to create charcoal from solid wood in a primitive low-oxygen furnace - that would be useful.

Even without metallurgy, I could probably cook on slates and stones, or create pottery solid enough to boil water. If I’m around during or after the Iron Age, I’ve got all the cast iron I could want.

Ingredients would probably be limited. My knowledge of food chemistry would definitely help. Without refrigeration I’d have to rely heavily on pickling and salting. If I could learn glassblowing, we could move on to canning as a preservative.

Yeah I can go pretty damn far back. (username)

Chemotherapy.

You mean they poisoned people in hopes that the tumors died before the person did? Wild!
