Climbing alone, or "solo climbing," is very dangerous.

VOA: special.2009.12.09

It might be very important and insightful, but you're not saying anything especially interesting about death when you say everyone dies alone, if it's also true that everyone eats their lunch alone.

很重要，很有见地，但这样提出每个人都孤独而死时,并未对死亡本身提出什么有趣特别的见地，因为说每个人都孤独地吃中饭也是对的。

I put these conditions down because,of course, what I want to suggest is although the sentence everyone dies alone, the claim that everyone dies alone, is one of these things that people say, they're not really thinking very hard about what they mean by it.

我定下这些条件是因为，我想说尽管大家都说，人孤独而死，这都只是说说而已，人们说的时候并没有做什么深刻的思考。
