Meh he always talked like that. Back in 09 he was talking about the sport not being fun, once yohan beat him, it lit a fire under his ass. I think he really wants rio now and the fact that he will be 30 he thinks it will be more of a challenge. Truth be told, as long as his body doesn’t give out on him, he can keep running amazing times well past 30. As you can see now in many sports…age don’t mean shit. Also I read a story a while back that men peak in strength in there 30s. So as long has yohan is running fast and the few Americans that can almost compete with him, he will keep doing it. Asafa, gay, Gatling all still have the chance to drop fast times. Age ain’t nothing but a number…don’t forget linford and Marlene and all the other 30 plus athletes.
