I am a late 30s American.
As a youth I played football, soccer, basketball and baseball. Football is the sport I liked playing the most and played the longest into my teens. Basketball and soccer I never liked - too much focus on small, solo coordination skills. And baseball was OK but I played catcher and really appreciated being involved in each play. If I didn't play catcher I doubt that I would've liked baseball as much. But baseball has a kind of "mystic" that I find appealing. It is different than other sports.
As far as my upbringing goes, my father received a college football scholarship. He didn't play much at that level but he was good enough to get one and be on the team. Football was therefore the primary sport in my household in terms of spectator entertainment and overall knowledge.
I don't play organized sport anymore and I am now primarily a spectator/fan/consumer. As a spectator, I find that hockey, soccer and rugby are the sports that I like the most. They are fast paced and exciting because each one can leave you on the edge of your seat and require fitness and skill. As far as football goes, I still think that the NFL is a pretty good entertainment "product" but that's really what football feels like to me. Almost no one plays football. There aren't pick up games and I have never heard of a recreation league. It feels more like a spectacle than a sport. It's like the NFL is to sport what Broadway musicals are to art... kind of ridiculous. The pads and helmets, the breaks in play, hundreds of coaches, the incredibly specialized positions, the huge squads. It's all too much. I kind of think it's a farce.
Now my child is a girl. I have never heard of girls playing football. I know that there is the odd girl on a high school football team every now and then but there are not girls' football leagues. But women play rugby! Lots of people play rugby. It is an international sport for people of all shapes and sizes that includes running and physical play on a big grass field. FUN! As a parent I am interested in rugby and wish that I knew about rugby as a young person.
