I agree with everyone else about the physical hobbies, but I find you need something else to fill the evenings when you don't necessarily want to go outside, or when you just want to spend half an hour doing something that's not coding and not reading.

Music does that for me. If you're at all interested, check out justinguitar.com (no affiliation, just love what the guy does) and try it out. There's something about the meditative aspects of playing music that really works for me.
