I feel like any time I read a wikipedia page about some historical figure born around then they always are described as "sickly" in their childhood. Like fuck, weren't there any health kids back then running around with those hoops and the stick or singing creepy songs in fields and... idk whatever the fuck else kids did back then, commune with black goats who send them on wicked errands to corrupt their soul to the dark prince?
Lack of vaccines/child labor/malnutrition? Inbreeding in case of royals, who would be healthy there :shrug-outta-hecks:
Shit, how did we make it to now with everyone dying and miserable?
Lots of kids
no evidence that those people actually did "make it to now", tbh. I'm sure many did, but I'm also sure that if you were to do a full geneological analysis, that many of those people died without reproducing, similar to the neolithic genetic bottleneck
It was mostly densely populated cities which had plague problems
