Music of course. I read a lot, am very left wing in my politics, and follow baseball as well, particularly the NY Yankees.
I'm particularly trying to get in touch with my old friends, but also want to meet new people who are into the same things I am.
Basically I like punk, soul, garage, all kinds of rock'n'roll etc. Not going to list any bands because there are so many. I'm trying to get back into seeing live music as much as I can, so I definitely am trying to keep up with what's happening on that front.
I used to be a film buff, now not so much. I particularly love old films, Bogart is my favorite actor. For contemporary films I like most film genres, even Hollywood stuff except comedies, romantic or otherwise.
I read a lot, Mostly I read genre fiction, mystery and sci-fi. I like hard-boiled, noir, detective novels, and contemporary sci-fi without too many space battles. Think Raymond Chandler, Phillip Kerr, Michael Connolly and Lawrence Block on the mystery end. For sci-fi, it's Ursula LeGuin, Dan Simmons, John Varley, early Orson Scott Card. I read a lot of classics as well, most recently all of Tolstoy's novels, and just read Lolita by Nabokov.
