I try to think about how I'm glad I wasn't born any time in the last 2000 years (any time after the agricultural revolution), otherwise if I didn't die as a kid of some horrible disease, I'd live to either die in childbirth, starvation, or watch most of my kids die of said diseases/starvation.

Generally the best time to be born was 10,000 years ago when we were still living the lives our brains and bodies are adapted to, or now when we've at least got vaccines, warm houses and comfy beds, and things like music and math and psychedelics and access to every book ever and strawberries or whatever else you happen to enjoy.
