Music also plays a big part in my life. I let Last.fm be the DJ. I play trumpet in the fanfare (kind of brass band) of the town I grew up in. I arrange music for the fanfare. I also play guitar and keyboard.
For a living I am a programmer, which is also still a hobby. I love it because when you have to do the same thing more than once, you can automate it! The more abstract it gets, the more I like it.
I didn't do sports the first 30 years of my life, but now I do climbing. I also like a nice long walk, bicycle trip or ski holiday, even more so if it involves nice scenery.
