I am better now, as an astronaut in my 60s, than in my 40s because it’s a very complex business in which experience and perspective play a lot. You tend to scope out. You tend to know ahead of time what you’re going to have to learn to get that job done. It’s not a stick and rudder, it is not an instinctually reflective thing. You don’t just jump on things, you’ve got to study them. And it’s a very complex business in which experience counts. I create a lot of hope for people because they see, in fact, that not only am I better in my 60s, but I’m having more fun. They see a richer life. And so, I’m even amazed myself. I’m even amazed, too, that life is so much better in my 60s than my 20s.
