From an article entitled 'Jamaica's Miracle - Myths, Legends and the Making of Usain Bolt', by by Alexander Osang and published in der Spiegel:
[ The other athletes were mere accessories, Olympic and world champions playing the opening act for the fastest man in the world. The journalists were interested in only two other athletes. One was Oscar Pistorius, who is running the 400-meter race on prosthetic lower legs, and the other was 800-meter runner Caster Semenya who, for a time, was rumored to be a man. ]
The woman without a womb, the man without legs and the sprinter without limits; they're all competing in the London Olympics. It's the biggest circus of the day, and these are the star attractions.
