We’ve all seen some amazing performances during the Olympics the last two weeks. We’ve seen athletes display amazing abilities. The question in my mind right now is, just how far can these athletes go? Remember when a sub 4 minute mile was unthinkable? That is until Roger Bannister ran one? Remember how it used to be watching the men’s 100 meter dash? Then Usain Bolt came along and started blowing everybody away. Today’s athletes routinely perform feats that were unimaginable when I was a child. Just how far can they go? With the ever growing amount of research and knowledge into sports performance, are we nearing the limits of human potential? Or have we just scratched the surface? I personally hope that the latter is the case. If it is, the next 30 years are going to be loads of fun.
