I never did any sport simply because I never found any I liked. Never was very competitive anyway. I do like hiking though, and used to play a lot in the outdoors as kid. I don't find sport very interesting on TV either. Soccer is the big thing here, and it is horribly boring to watch. I do like watching the winter Olympics though. Something special about the extreme endurance of the cross-country skiers.
Personally, I'm quite into sports. I like ice hockey, football, baseball, basketball, tennis and motor racing (MotoGP and F1). Hooray for being a jock! (I don't play any though)
