Next four years

So Bolt didn't break the world record. He ran in a 'slow' time of 19.32sec in the 200 m. Still it was enough to win him the gold. The first time in the history of the game that someone was able to defend both the 100 and 200m title. A mighty achievement indeed! Can he do it again in four years time? Let me put my neck on the line by saying no. I think, somebody will challenge his domination within the next four years. Already we are seeing the early signs. And who is that person? That person will be Blake, his training partner, the silver medalist in both the 100 and 200m.
