Today, one in 10 men in the NBA is at least seven feet tall, but a seven-foot-tall man is incredibly rare in the general population -- so rare that if you know an American man between the ages of 20 and 40 who is at least seven feet tall, there's a 17 percent chance he's in the NBA right now.
今天，NBA里十个人中就有一个人 至少七英尺高， 但是一个七英尺高的人在普遍人口中 是不可思议地稀少 -- 稀少到以至于如果你认识一个美国人 年龄在20岁到40岁 身高至少七英尺， 那么有百分之17的几率 他就在NBA里。
