The cruelty of nature is you have to work out harder when you get older ... It should be the other way around: Work out hard when you're a kid you should be able to coast when you get older. But unfortunately you have to do more to stay in the same position.

I'm past doing one chin-up more than I did the day before. I just kind of do what I feel like.

Kids piercing themselves, piercing their tongues, what kind of masochism is that? Is it to show you can just take it?

And I think it's that time. And I think if you just step aside and Mr. Romney can kind of take over. You can maybe still use a plane. Though maybe a smaller one. Not that big gas guzzler you are going around to colleges and talking about student loans and stuff like that.

I believe that everybody, whether you believe in the afterlife or the chance of a near-death experience and you come back and you see someone [on the other side] - whether that has happened or not, I don't know, but certainly everyone has thought about it at some point or another in time. It's a fantasy that if there is anything out there like that, it would be just terrific, but that remains to be seen.

It takes tremendous discipline to control the influence, the power you have over other people's lives.
