We've joked about having the right genes for happiness, but it turns out that we might have just that. New evidence from the emerging science of epigenetics shows that there is a complex interplay between some of our key regulatory genes and our emotional state. In this new book, Dawson Church presents, in simple, non-scientific language, the latest research on how your mental state affects these genes. He shows how belief, intention, forgiveness, meditation, altruism, optimism, and other attributes of happiness can exercise a powerful effect on our stress genes. These genes are involved with aging and immunity and by changing our emotional state to a happier one, we turn on the genes that promote better health and longevity. He shows that the effects of these emotional practices can add many healthy years to our lives.
