Usain Bolt vows ‘never again’ after emotional London farewell

Usain Bolt took an emotional final bow on the track at the end of the World Championships in London on Sunday before declaring that, definitely and definitively, there was no way he would ever return to sprinting. After embarking on a special lap of honour so slow that you could not believe that we were saying farewell to the world's fastest man, Bolt was asked by reporters already missing him whether he might ever change his mind. “No, I've seen too many people come back and make things worse and shame themselves. I won't be one of those people who come back,” Bolt said firmly. (Video: SNTV)
