Shields has got won it by 19-12. No one could dispute that score. As she leaves the ring she does a little Ali shuffle and then starts mock brushing her hair back. You can almost imagine her saying: "Look at me, I'm so pretty!" At 17, she's the second-youngest boxer ever to win gold at an Olympics. If she was a male boxer, greenbacks would follow gold. She'd inevitably turn pro. But I'm not sure what will happen next. But whatever happens, she's a star. A genuine star. Thanks for all your emails and tweets. Best, Sean
