Books: Oh dear god, this section generally takes up half the
profile. As mentioned above, I read a lot, and I own a lot of
books. I love history (especially when the book goes deep into the
subject), I love science, I love spy novels (so much!), I love
science fiction (Iain M. Banks, Philip K. Dick, Neal Stephenson,
many many many more), I love (some) fantasy (too much fantasy reads
exactly the same for me to be more general there)... And that's
just the tip of the iceberg.
Movies: I remain convinced that Lawrence of Arabia is the greatest
movie ever made, and that Groundhog Day is the best movie of the
TV: The Wire, Community, Futurama. I used to watch a lot more TV,
but at some point in the last couple years, I lost interest in most
Music: I'm fairly sure I qualify as an Old Person as a result of my
music tastes: pretty much everything I listen to is at least 10
years old. And most of that is British. I saw Pulp in 2011 in
London - I set up an entire trip to Europe primarily so that I
could make it to that show. The show, thankfully, given the effort
involved, was fantastic.
Food: I love Indian food. I like a lot of other foods. But I'm not
the most adventurous eater in the world - I was raised on bland
'50s style cooking and my palate still hasn't quite recovered.
