My sports fanaticism has varied. I played sports all the time in h.s. -- soccer, track, cross-country skiing (hey, it was Minnesota.) Track was the only one I was really good at. Sprinter.
My dad has always played pick up b-ball, (he lives near the Timberwolves training facility and plays with some players occasionally (!) -- little Jewish 60-yr-old) and I would go watch when I was a kid, shoot around with him a bit. I never really liked organized girl's basketball teams, though. Too nice. They didn't like "no blood, no foul" .

Never got into pick up seriously until I was in college. Spent a summer at home playing, really got into it, and got pretty good. For a while there I was playing 2-3 hours everyday, with guys. Long enough ago that I was a novelty -- pre-WNBA. Probably couldn't get away with it now. (I depended on the guys laying off, not defending me too closely, then I'd have a wide-open three and take it -- once they figured out I could do that, I'd fake a three, they'd come up to block it, and I'd duck under and drive in for a lay-up. Once they figured out I could do THAT, I was finished for a while unless they decided to humor me or I got a steal. I was always the shortest and weakest player, but scrappy on defense. Occasionally there was someone as short and weak as me, or maybe a little lazier, and then I'd get to really play, and that was SO fun.)
In terms of watching sports, I've really drastically cut down, and that has a certain snowball effect. Like, I haven't seriously watched the NBA for a while, so I've lost track of who the players are, and don't know the new guys, so am less interested... etc. Still have to watch the Packers if they're on, though. That'll probably last until Brett retires, then I dunno.
