With which average lifespan and enduring what pain? What was the solution for, say, a tooth going south?
Medicine was ugly back then. Between 1% to 1.5% of all the woman giving birth would die while doing so in 1600. Something insane like that. We've literally gone down at least 30x.
Also back then women couldn't really decide whether they'd become pregnant or not.
At 17 years old or so I got a medical emergency: doctor diagnosed an appendicitis that was missed a few days earlier for I was under strong painkillers. When it was diagnosed a few hours later I was undergoing surgery.
In 1600 I could very well have died of peritonitis / infection without the surgery. I see all those years I lived since then as pure win, thanks to modernity.
It comes at a cost but I live better than any king has ever lived (except for those who live/lived in modern times).
I had a terrible fever when I was 3, I probably wouldn't have made it if it wasn't for modern health care. Beyond that, though, I've only needed modern healthcare for ailments caused by modernity: Tooth problems from sugar and not chewing enough, and also I was hit by a car.
Talking about cruel healthcare practices, though, can you imagine being on your back with a tube shoved down your throat for weeks while you slowly suffocate to death like some of those peeps in the COVID wards?
3 of my 4 grandparents are dead, and all but one died in slow, drawn out and excruciatingly painful ways.
There are tribal societies that have been stable for tens of thousands of years. Modernity is an inherently unstable system.
