Once when I was a teenager I happened to say to one of my parental units (can't remember if it was my mum or dad) that I'd never seen a dead body. The parent stopped and stared at me, as if such a thing had never occured to him/her. "You've NEVER SEEN A DEAD BODY???"

I must've been a quite young teenager because later I saw a dead body on the street in Philadelphia (not terribly close up) and I saw someone who must've been close to death on a NYC street around that same time -- I've never seen anyone that shade of green since. It's quite astonishing the strange colors people can turn.
