Impossible to list it all without this being huge, but here's a few
samples from each area:
Books: "Good Omens" is probably my favorite book. Anything by
Gaiman, Vonnegut, Steven Brust, William Gibson, or Brandon
Sanderson. I'm all over the place, but mostly read fiction.
Recent good reads:
Pages From the Textbook of Alternate History;
Someone Could Get Hurt: A Memoir of 21st Century Parenting;
Wisdom; Compassion; Serenity: First Steps on the Buddhist Path (not
a practitioner myself, just find it interesting;
Redshirts; The Magician King (see above re: geeky)
(I really tried with Swann's Way recently, but only got about 10%
through, need to go back eventually)
Movies: Comedies are generally my favorites, but A Few Good Men,
Raiders of the Lost Ark, Big Fish, Tombstone, Kiss Kiss Bang Bang
and Star Wars are some faves.
TV (All time): Coupling (UK), Firefly, Pushing Daisies, The
Simpsons, BSG (remake), West Wing;
Music: I'll listen to just about anything, but Social Distortion,
Weezer, Bad Religion, Rise Against, Jamiroquai, and Me First &
The Gimme Gimmes are some that I can listen to at just about any
time; a lot more upbeat stuff and hip-hop now make up the majority
of my playlists b/c of the gym.
Food: Spicy tuna rolls, NY strip steak. I like to try new things,
though I did not try (nor did I come across, actually) the rancid
shark meat on my trip to Iceland. I love cooking, but kind of hate
that my kitchen is too small.
