I wholeheartedly agree. Also, I think being involved in organised sport does wonders for social skills. I competed in athletics from a young age, and always knew people of all ages and backgrounds. I'm still friends now with an older girl I trained with as a child and through adolescence (actually she's the coach I spoke to for the ready for ten post I did on athletics!)
As you say though, sport doesn't have to be organised and competitive, there are plenty of activities that are just for fun. Roller discos were big back in the day!
