Mariel Hemingway introduces her new book, Healthy Living From the Inside Out. In this wide-ranging and challenging interview, the actress-turned-author explains how any woman can live a balanced life by making key choices in four particular areas: eating; exercise; silence; and the home environment. Hemingway goes on to talk about how the 28-day plan she lays out in the book is the result of her own 30-year journey of discovery.
