Usain Bolt proves that humans can fly

Congratulations to Usain Bolt who has consolidated his position as the world’s fastest man. Taking just 40 strides, he re-writes the record books for the third time. Isn’t it amazing how the human body can move, when it has a clear purpose.

In the graph below, I have plotted how the 100 metre record has reduced since 1912 (when records began).

As you can see, it has taken around 100 years for the record to fall by one second. So, with a little luck, my children should still be around to witness the next second.
