Lightning quick

His nickname is Thunder but yesterday Usain Bolt was as quick as lightning in lowering the 100m world record by 0.02s. He's the world junior record holder of the 200m, which he set at the age of 15 and he looks like he may be the man to beat at the blue riband event in Beijing. Lets hope he's keeping something back because that's the second 9.7(x)s he's run in the last four weeks.
