Why is Usain Bolt the greatest athlete you will see in your life ? It's not only because of his  records, it goez beyound that. Sure, runing the 100m in 9.58 seconds and the 200m in 19.19 seconds is quite intersting, but i's what he brings to the sport that gives him the status of legend. He looks so relax and confident before the race and the smile he have after his races make him really fun to watch. He revolutionized sprinting not only with his legs, but also with his mind.
