I don't watch team sports on TV. Unless it's socially, and only football, soccer or hockey. Individual and extreme sports like kick-boxing, snowboarding, etc. would interest me on TV, but I don't subscribe to a cable service.
I don't like baseball at all, but I do enjoy going to games. I see NFL and NHL games here and there, and will go to a NASCAR event and enjoy them immensely even though I almost never see the actual race.
Older now, so I don't participate in as wide of a variety of activity as I used to. In the summers I like to wake board, play golf and swim. Do some motorcross or cycling... In the winter I like my kettlebells and cross training intervals.
I might play soccer with an adult league this spring.
