Former UFC lightweight and welterweight champion B.J. Penn is too old for this you-know-what.
He's still a proud man and a fighter. But he's a father of two now, and
has children to keep in check the flare-ups of emotion that would have
landed him in hot water three years ago. He can't go flying off at the
handle at any slight. He is measured because he is responsible.
In short, he's an adult. At 32, he ought to be.
