I guess the last time we had to hang around it was so unbearably cold all we could do was get into our sleeping bags to survive.

我猜这是因为，上一次我们被迫停工的时候，天气冷得简直无法忍受，我们唯一能做的就是钻进睡袋里熬过严寒。

The work is physically exhausting, mentally numbing and often performed in filthy and unbearably hot or cold conditions.

这些工作往往使人身心疲惫，而且往往在肮脏并且令人难以忍受的酷热活着严寒的条件下工作。

And why not? Imagine how unbearably, how unutterably cold the Universe would be if one were all alone...

为什么不这样呢？想象一下，在这个难以忍受的，非语言所能形容的寒冷的宇宙里，如果一直孤孤单单。
