当我们饿了的时候吃饭，渴了的时候喝水，累了的时候睡觉。

We ate when we were hungry, drank when we were thirsty, and slept when we were tired.

不要饿了才吃饭，不要渴了才喝水，不要困了才睡觉，不要累了才歇息，不要病了才检查，不要老了才后悔。

Don't eat until hungry, Don't drink until thirsty, Don't sleep until sleepy, Don't rest until tired, Don't be examined until sick and Don't repent until aged.
