No one looking at Jane Fonda today would consider her “over the hill.” The seventy-three-year-old author, actress, and workout pioneer looks to be in the prime of her life. In her best-selling memoir, My Life So Far, Fonda focused on the first half of her life – which she calls Acts I and II — with an eye toward preparing for a vibrant Act III. Now, she has written a new book that explores how this third act can be an opportunity to become the people we were always meant to be. She explores how re-thinking exercise, diet, and relationships can transform the so-called golden years. Jane Fonda talks with Diane about her life today and why she is the happiest she’s ever been.
