In an attempt to measure Americans' health, happiness and satisfaction with life, research company Gallup has teamed up with Healthways, a disease management and health-coaching firm, to create a new way of measuring well-being. The Gallup-Healthways Well-Being Index will look at Americans' overall well-being for the next 25 years. Dr. Oz talks with Gallup's Jim Harter and Katie Bell about the study, sample questions and some of the study's immediate findings.
