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.

Frankly, as much as I love to improvise, it hasn't been difficult to stick to the script on 'Mad Men.' The writing is so precise, and the story so carefully crafted, that I don't think there's room - or need - for ad libbing. I could never come up with dialogue as lovely as these writers do, anyway.
