Former Olympic sprinter Usain Bolt, freshly retired, doesn't have much concern with his world records falling anytime soon.
The six-time Olympic gold medalist holds world records in the 100 meters (9.58 seconds) and 200 meters (19.19 seconds), both of which he set in Berlin in 2009.
"I think (they're) going to last awhile," Bolt said via the Associated Press during a promotional event Tuesday in Japan. "I think our era with Yohan Blake, Justin Gatlin and Asafa Powell and all these guys was the best era of athletes. If it was going to be broken, it would have been broken in this era, so I think I have at least 15 to 20 more years.
