Haven't watched F1 since HΓ€kkinen called it a day. Proper racing those days.
I can't stand most American sports. Although I do follow the NBA a little. European basketball looks like amateur league in comparison.
Myself, THE sport for me has always been Judo. Used to compete during my school years. Won a couple of national championship medals even. Still very passionate about it though, I attend most big tournaments in my area.
I occasionally watch some Snooker, Track and Field, Hockey and Volleyball, but that's about it for me.
Oh, and there's football of course...
