Exercise is more important than diet for me because it's a twofer. It keeps me in good physical shape, and it relieves stress. And when you're a representative of the public, there's never a shortage of things to do.

When people said Africa would change me, I didn't understand what they meant. To see the poverty in the townships, for instance, is overwhelming. I found it heart-wrenching to see young children walking barefoot and hungry in the dirt. I'm the kind of person who wants to change the world right here and now, so I got frustrated.
