Putting the lightning back in Usain Bolt

Usain Bolt is back in old London town and that is usually good reason to be cheerful, not fearful. 

Today, the fastest man on God’s earth will breeze into a hotel next to Tower Bridge and tell us all that he’s cool, that everything’s cool and that, hey don’t worry, the real Usain will be back in business at the Olympic Stadium on Friday night.

Except that some of us do worry about Usain. We worry that, at the moment when his sport needs him most, a sport hamstrung by cynicism and scepticism and populated by a cast list people do not believe in, Bolt may have mislaid his red cape.
