我想在太空飞行，绝对的！那会是相当酷。我自己过去经常做一些冒险的事情，但是我现在有了孩子和家庭责任，因此我没法拿自己去冒风险了。那样做不明智。但是只要太空飞行变得切实可行，我一定会去尝试。

I don’t regret anything I’ve ever done in my life, any choice that I’ve made.

The other thing about modern society and why it causes this anxiety, is that we have nothing at its center that is non-human. We are the first society to be living in a world where we don't worship anything other than ourselves. We think very highly of ourselves, and so we should; we've put people on the Moon, done all sorts of extraordinary things. And so we tend to worship ourselves.
