Former tennis-player, John McEnroe, was famous both for his skill, and his legendary temper tantrums. He became famous for the saying “you cannot be serious!” (He later claimed he only said it once).
His outbursts often resulted from the feeling that he was being wronged – whether or not it was actually the case. But it was so bad, that eventually earned the nickname “Superbrat.”
Would it surprise you to know McEnroe’s reaction was in all likelihood, biologically wired?
