These other existences of yours go on quite merrily whether you are waking or sleeping, but while you are awake ordinarily you block them out.

无论你是醒着还是睡着，你的这些其他存在都非常愉快地继续着，但当你醒着时，通常你会把它们拒之门外。

In man, breathing is incessantly going on—one breath only serving for two or three pulsations; so that whatever other business he has to attend to, waking or sleeping, breathe he must, or die he will.

就人的情况来说，呼吸是不间断进行的—一次呼吸只能维持两三下脉动；以至于无论他在做别的什么事情，是行走还是在睡觉，他都必须呼吸，否则就会死掉。
