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?
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
