it's impossible to overemphasize just how many things could kill you in the past
the life expectancy was in the 30s for a lot of it not because you were Old At 30. but because:
A. so many children and infants died (SO many)
B. there were. WAY more things that could kill you. diseases that are surviveable now. injuries, ditto. freaking childbirth (don't get me STARTED on childbirth. both of my friends who have kids would have died before surviveable c-sections probably)
I probably would have died of an infected cyst on my arm at age 15, before antibiotics. or lost the arm. that's assuming the croup didn't get me when I was seven. and furthermore that I didn't get any of the things we vaccinate for now
also like. I don't know. my brother died at one year old of a rare complication from, basically, a cold virus. that's impossible to detect without tests nobody is going to give a seemingly healthy baby. he died in 1992 and there was nothing anybody could have done to stop it. and no matter how expected it is in one's society, I cannot believe it was ever any easier than it was for my family. it changes you, in ways you'll never be able to reverse. I was born after his death, and even I felt the negative space of his absence in our lives (though I will say that my parents handled it exceptionally well in my opinion)
my father still talks about wanting to be cremated and have the ashes scattered on his grave. thirty-something years on. my grandfather stopped believing in God when he died. and I want to emphasize that there was nothing, nothing that could have saved him. imagine a child dying of something you COULD prevent
the fact that some people would go back to a time when this was commonplace is just insane to me
