My old uncle, who I like to quote here every so often, was out plowing with his prize bulls one day. Pretty amazed, I yelled, "Uncle, uncle, why are ya plowing with your two prize bulls?"
He answered, "Well, I don't want 'em to start thinking that life is all fun and games!"

Extrapolating, I've always figured that a little early pain might be a good instructive lesson for the kids!! ;-)
