It's the most glamourous of sporting events -- the men's 100-metre sprint.
It is about speed and skill, muscle and mind, all coming together in one adrenalin-pumping, lung-bursting, explosive effort aimed at breaking the barriers of human physicality.
There was a time when a 10.4 second sprint produced gasps of awe. Today, 10.4 seconds wouldn't get you into an Olympic final.
So ask yourself this -- will the day come when the nine second barrier is shattered?
If that sounds impossible, check this slide show out. Trace the evolution of the sprint record. And you will probably find reason to believe that when a determined man gets set on the starting blocks, anything is possible.
