When you're that successful, things have a momentum, and at a certain point you can't really tell whether you have created the momentum or it's creating you.

When you get to be nearly 60, you do take stock. You don't know what's around the corner.

If you do nothing, if a mother doesn't come for care, if she breastfeeds her baby, the chances of the baby getting HIV are about 40%. So it's about the difference between 40% and zero. This is almost totally preventable. But it requires mothers coming for care and getting the medicines they need, and getting the education and support they need.

I wasn't trying to be a role model for anybody. I don't think that you can.

If someone says something unpleasant, I can't say it doesn't smart a bit. It always does. Someone can take a really nasty swipe if they want because it kind of feels powerful for a person to write in a paper and get that thing out there.

I'd rather support the issues I truly believe in than give my vote to parties that court votes at the time of the election. I like to think that my vote strengthens the green foundation stone.

I haven't lived my life through my daughters. Some parents devote everything to their children, which must be so hard, and it's very beautiful. But I'm a working parent, so I've always kept my own life.
