If I could meet 5 dead people they'd be (in no particular order): Sagan, Lincoln, MLK, Hendrix and Cordwainer Smith. Each of them has influenced my life and opinions in such a way that I wouldn't be the same person without them.
I'd like to go back in time and visit medieval England, but an alternative version of England that has no completely awful plague that wiped out a third of the planet. Mostly because I dislike rats, never mind the mass death. Rats, man.
I like being a cornucopia of random knowledge and facts. I like trivia games. I can usually beat my friends at Trivial Pursuit, but I think that's more because they're bad at it than I'm any good. We'll keep that last part just between us, however. :)
