Is curly hair a dying breed?

I took my son to karate last night and in a room full of people, we were the only ones with curly hair. No other parent had curls and neither did any of the 30 boys and girls. With his arms and legs thrashing around, the curls on his head bobbed around, but I was surprised no other child had even a kink in their hair.I Flounders calls it the devils curly hair in the Simpson's movie, but is it really? Is naturally curly hair a dying breed ? Ruth@HJi x
