Books -- I read a lot, and have a strong inclination towards
literary "brain food". Some of my favourite authors are Douglas
Adams, Scott Adams, Stephen Baxter, Mihhail Bulgakov, Isaac Asimov,
Arthur C. Clarke, Peter Hamilton, Robert Heinlein, Terry Pratchett,
J. R. R. Tolkien, and many others. A significant part of my library
is in English. I try to buy only the books I expect to read more
Movies: I'm not a big movie fan, although I tend to sleep less than
normal during the Black Nights Film Festival (PÖFF). I often find
good documentaries and educational programs worth watching.
Music: mostly rock, metal, or classical. Occasionally some kind of
ambient, or older pop.
Food: I like sushi, Chinese, and Mediterranean cuisines, fish and
meat, and of course black bread.
