Learn to Live Longer, Do Mental House Cleaning & Be a Vegan

My guests today are Dr. Jonny Bowden, author of "The Most Effective Ways to Live Longer"; Dr. Tomas Lafayette Picard, author of "Mental Housecleaning: Attitude Adjustments You Can Do in the Comfort and Privacy of Your Own Mind"; and Alex Jamieson, author of "Living Vegan for Dummies." Alex has appeared on "Oprah" to discuss her "Great American Detox Diet," which helped her then fiance Morgan Spurlock, the director and star of "Super Size Me," who lost lots of weight after pigging out on burger and fries for the film.
