这很像一个不吸烟的人因为二手烟而得癌症，而烟瘾大的人即使吸烟也幸运地保持健康。

This is much like a non-smoker getting cancer from second-hand smoke, while the heavy smoker is fortunate enough to smoke in good health.

我为得癌症的是她而不是我，我不能替她死感到痛苦。

Yet I ached to take the cancer from her; even to die instead.

现在如果我们看看烟民,有人得癌症，有人没有，不是吗？

Now if we look at smokers we see that some of them gets cancer and some of them don't. don't we?

It was easy to tell if somebody had an infectious disease but you might not have known that they had cancer at that time and they just died.

如果有人患有感染性疾病,那很容易判断,但在那个时候医生可能不知道,病人得的就是癌症,病人就这么死去了
