Also, finding new hobbies. If something sounds remotely interesting, I'll typically invest more time in it than is strictly necessary.

I'll eat just about anything, though. There's not much out there that I don't like.
Caffeine - I drink far too much tea. Coffee, too, but mostly tea.
Music - I almost always have Spotify playing in the background, either on my computer or my phone. My tastes are broad enough, though, that I'll listen to anything.
Books - I read far, far too much, especially since I discovered I can read on my phone instead of the dead tree edition. The only trick is finding enough books to actually sate my appetite (which is pretty much impossible anyway).
Dog/Cats - I love animals. I grew up with at least two dogs in the house, and have two cats since they won't develop personality disorders when I'm away at work 10 hours a day.
