Jane Fonda

I've done four videos for older people under my new brand, Prime Time, and the missing link was yoga. I'm aiming it for older people - people who have never worked out or who are recovering from a surgery and have to start slow. It's easy, you can't get hurt, it's very doable, and I've done it in ten-minute segments.

The '50s in general are written off as a boring decade following the turmoil of the Second World War and its immediate aftermath - the postwar Labour government, the cold war, the arrival of the New Look in fashion, etc. But I remember it as a very exciting time - a pioneering, rule-breaking time, especially for the young.

The importance of heart health became very real for me when my father died of heart disease seven years ago. Having experienced the loss first hand, I am inspired to do everything I can to break the cycle and prevent families from losing loved ones to this preventable disease.

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.
