Stories. Pretty things. Themes and concepts like: idealism. Ordinary people driven to extreme acts by principle, love or circumstance. Sacrifice. Mysticism. Degradation of character.

Literature in general
Religions
Sexuality and homosexuality interest me as subjects to learn about, but I'm also at my prime so sexuality interests me as a rule anyway

Gardening
Knitting (very passionate about knitting, almost unnaturally so)
Human behavior as one progresses from age group to age group
Probably most importantly: the environment

Well Matazone, obviously

I've wondered about that too..

Music
Films
Psychology
Physics
Diabolo/Juggling (even though I suck at them)
Dreams

Theres actually lots of things I find interesting, I just dont know anything about most of them.

Music (various forms of rock - the search for the perfect song)
Computing and the future of, particularly in the field of AI
Juggling. Some day I'll be able to juggle four balls.
Philosophy. So there's no God. I'm cool with that, but how the hell am I supposed to know right from wrong?
Mythology. Greek, Norse, Egyptian, Christian; you name it, I love it.
Euthanasia/Assisted Suicide. Not the practical side, but ethics and psychology of it. After previewing, this seems an odd thing to list as an interest. But hey, I wouldn't appreciate my life so much if I wasn't so morbid.
Minesweeper. No greater game has ever, or ever will be invented.
