Mark McClusky says for elite athletes today, pushing boundaries and breaking records is all about "the aggregation of marginal gains."
A powerful 23-foot tsunami spawned by the largest earthquake in Japan’s recorded history slammed the eastern coast Friday, sweeping away boats, cars, homes and people as widespread fires burned out of control.
Japanese authorities say 200 to 300 bodies have been found in the northeastern city of Sendai, the closest major city to the epicenter of the 8.9 magnitude earthquake.
The offshore quake was followed by more than a dozen aftershocks, most of them of more than magnitude 6.0. Dozens of cities and villages along a 1,300-mile stretch of coastline were shaken by violent tremors that reached as far away as Tokyo, hundreds of miles (kilometers) from the epicenter.
