How Our Genes are Hurting Us

Guest: Lee Goldman, MD, Dean of Medical School at Columbia University  We have some bad news about our health: our genes are out to get us. Traits that our forefathers needed to survive in a violent, dangerous world now conspire to cause the diseases that explain nearly half of all deaths in the United States: obesity, diabetes, high blood pressure, heart attack and stroke--even depression and anxiety. Dr. Lee Goldman explains how this works in his new book, “Too Much of a Good Thing: How Four Key Survival Traits Are Now Killing Us.”
