If I'd been born in the Middle Ages, I think I'd probably be dead or at least half-blind by now. I've had quite a few bouts of tonsillitis and bronchitis, and eye infections. Or I might have died in childbirth without the forceps delivery, but I doubt it.

Of course, I wouldn't have my daughter, because her father's asthma would have killed him well before we met.

I do like your point about how our social needs really don't change much, though.
