But it possible - if is statistically extremely unlikely - that Steel could be born a " short sleeper" with an unusual body clock, says sleep expert Dr. Sophie Bostock.

睡眠专家索菲·博斯托克博士说，但有可能——尽管在统计学上极不可能——斯蒂尔可能是天生的“短睡眠者”，有着不寻常的生物钟。

Even if Steel does happen to be among that tiny minority, says Bostock, it's " pretty irresponsible" to suggest that 20-hour days are simply a question of discipline for the rest of us.

即使 Steel 恰好是那极少数人中的一员， Bostock 说，认为每天工作 20 小时只是我们其他人的纪律问题也是“相当不负责任的” 。
