他对美国国家公共电台的记者说：“情况就是这样，女性常因为工作上的事情而长期睡眠不足。”
But he added many women don't see their early bird tendencies as a problem.
不过他也补充说女性朋友并没有意识到早起也是造成她们失眠的原因。
He said: "There are many women who really enjoy the fact that they can get up at 4 or 5 o'clock in the morning. They have peace and quiet. Before the rest of the world wakes up, they can get an extraordinary amount done - and they wouldn't trade it for the world."
他说：“许多女性朋友很喜欢早上四、五点钟起床那种感觉。她们感觉内心平静安宁。当周围的一切还沉浸在梦乡中时，就处理好了一大堆事情——她们可不愿失去这种感觉。”
