Sumo Wrestlers Hard to Find: The amount of

new blood in the 1,500-year-old Japanese sport of sumo wrestling slowed to a single drop, reports The

Guardian, and experts are struggling to understand why.

Could it be that learning the sport is very

stringent, requiring boys to leave home to live in a "stable" with other wrestlers? Maybe. Could it be

that it's hard to earn a good living at the sport unless you make it to the very top? Perhaps.

But the

most commonly heard reason why there the number of sumo has dwindled to its lowest levels since 1958?

Japanese kids are too soft, preferring a life of comfort and ease to one of rigorous exercise and endless

chores, not to mention endless meals.
