You hit the nail on the head. I've lived with football fans most of my life and have been exposed to it plenty of times. Even when I try to pay attention to it, I find it so boring that I zone out and begin thinking about other things without even realizing it. I have no problem with people who enjoy football and professional sports in general, but it's just not something I have an interest in.

I feel the same way. I've absolutely no interest in football even after trying a couple of times. I've also lost interest in other sports over time. It may be something to do with growing older and having other priorities.

I was interested in certain sports as a teenager, but grew out of it. I can think of a couple of reasons. Firstly I moved around a bit, to different cities and countries, and parochialism seems very silly. If you don't care which team wins, a lot of interest in sport disappears. Secondly the sports themselves are extremely repetitive. Once you've learned the rules and seen a few games, there's not much more to learn, it's just variations on a theme.

Edit: I'm referring to spectating, not active participation. I'm sure there's a lot more to learn, understand and enjoy if you actually play.
