Well, I came from a family of sports fanatics. My dad had both baseball and football scholarships in college and was the club champion golfer for 14 years, my mother played basketball and ran track in college and coached women's basketball in high school when she became a teacher (though she taught algebra). My brother played basketball in high school and was a champion golfer (beat my father for one of his championships) and had a golf scholarship to college.
So, you can imagine how weird it was for this alien (read me) to drop in their midst who loathed sports and was totally into the arts. My dad MADE me participate in my town's swimming team (and I loved swimming so that helped), but I could never summon up much interest to participate in sports.
However, I was dragged to every Clemson football and basketball game there was, went to a lot of the tournaments once my dad retired from work and started playing golf on the senior circuit, and was taken to a more than average number of college and pro basketball, football, and baseball games.
That said, if I'm just watching sports, I'd rather it be figure skating, tennis, or gymnastics.
I've also discussed here before the enormous respect I have for men who box for a living. There is no more brutal way to earn a living, and though I can't watch much of it for long periods because of its brutality, the skill and physical acumen that these men must possess to do what they do is rather staggering.
