Usain Bolt: "These are the glory days"

Usain Bolt is a once-in-history athlete. On Saturday night, in the final event of the track meet, in what may have been his final Olympic race -- or may not, depending on his health and any number of variables -- he unleashed raw, primal speed.

Bolt and American Ryan Bailey, each man running the anchor leg in the men's 4x100 relay, got his baton at roughly the same time, in the lane next to the other. The race was on. But only for an instant. Bolt separated himself, with every step widening the gap, the crowd roaring with the roar of an airplane on takeoff as he hammered toward the finish line.
