I get heartfelt thanks from all kinds of people. Today I heard from a waitress in Georgia who has lost her job and is trying to figure out how her local bank can change the terms on her credit card, and I heard from a physicist at a major research university who wants to explain a better theory of financial stress tests.

People's view of cancer will change when they have their own relationship with cancer, which everyone will, at some point.

I want to be able to look back and say, 'I've done everything I can, and I was successful.' I don't want to look back and say I should have done this or that. I'd like to change things for the younger generation of swimmers coming along.

I wouldn't change a thing - except my bank balance.

No, nothing has changed in my life at all, and nothing would change if I had millions.
