One way to hold this phrase is to picture a clock with no face and no hands, sitting inside a living body and quietly running. Nobody winds it and nobody reads it, but it decides when the body gets sleepy, hungry, awake, or ready to grow. You only notice it when it disagrees with the clock on the wall - and if you can actually hear it , it is because something is counting down.
可以想成身體裡有一個鐘，沒有錶面，也沒有指針，安安靜靜自己在走。沒有人上發條，也沒有人看它，但它決定什麼時候想睡、什麼時候肚子餓、什麼時候醒得過來。只有當它跟牆上的鐘意見不合時，你才會發現它。而如果你真的聽得見它在滴答響，那通常表示有什麼正在倒數。
