XYY: Congratulations on your son's birth. I've followed xyy for decades, and the claim that these people are natural criminals is hogwash. They do tend to speak late, but so did some nobel prize scientists; nobody's reported hypermobile joints as a problem. Plusses include being tall and perhaps more assertive; acne's easy to treat nowadays. Take good care of junior, and cherish individuality.
