You are only on this earth for around 80 years, on average, if you are lucky, so why not try and experience as much as you can before you die.

平均来说，如果你幸运的话，你仅仅会在这地球活上大概80年。所以为什么不试着在你死之前经历尽可能多的经历呢。

youdao

If you're lucky, as another person; if you're not so lucky, as a pig or a donkey or an ant or what have you.

幸运的话，转世为人，如果不幸运的话，可能会变成猪，驴，蚂蚁等等。

You are so lucky to be where the sun is warm and not to have to face, as I do, an icy winter which lies heavy on your chest.

您在一个阳光明媚，气候温和的环境中是很幸福的，不像我这样，冰雪的严冬整个压在我胸口上。

youdao

If you're lucky, as another person; if you're not so lucky, as a pig or a donkey or an ant or what have you.

幸运的话,转世为人,如果不幸运的话,可能会变成猪,驴,蚂蚁等等
