I agree completely, but I also think it's okay to not be sporty. Sports are fun and healthy activities, but they don't really increase the chance that a person will attain great achievements as adult. It's a lifestyle and health choice.
I have a concern about a child being a sports kid more than an intellectual, if the child naturally tends toward being an intellectual. I don't actually discourage my son from watching sports, but I do inwardly hope that he doesn't grow up to be a sports nut (I'm talking mostly about watching and discussing sports here, not playing them). I just think it's a bit dull.
