Suzanne Sommers' 8 Steps To Wellness

We all know her best as the ditzy Chrissy Snow from "Three's Company," but Suzanne Somers is far more intelligent then the character she played so well.Since the sitcom ended more than 25 years ago, she's written 17 books, has gotten a star on the Hollywood Walk of Fame, and has sold more than 10 million thigh masters!

Her latest book is "Breakthrough: Eight Steps to Wellness," Somers shares just that - eight things you can do to get and stay healthy, and live longer."Breakthrough medicine," she writes, "is about building up our bodies to the point that we never suffer from illness in the first place."On The Early Show Friday, Somers reflected to co-anchor Harry Smith that she was "was interviewing a brain scientist and ... I thought it is so funny: I used to be Chrissy Snow, and I'm interviewing a brain scientist! But that's the reality of my life now."
