The six-time Olympic sprint champion called it “really bad news” for the sport after the announcement that 31 unnamed athletes were caught doping in retests from the 2008 Beijing Olympics.

Bolt said the World Anti-Doping Agency and others are doing a very good job of cleaning up the sport.

A video of the lesson from men’s magazine GQ is getting lots of clicks and laughs on social media.
