The "Happy Life" Scientist: How To FINALLY Beat Stress, Worry & Uncertainty! Dacher Keltner | E219

Dacher Keltner explains the emerging science of positive emotions and their measurable effects on health and longevity. He details how everyday awe, gratitude, compassion and physical touch calm the nervous system, reduce inflammation, and can add roughly ten years of life expectancy. He shares the personal grief over his brother's death that drove him to write his book on awe. The conversation also covers his research showing that rising wealth and social class tend to erode compassion and empathy, the loneliness and meaning crises driving declining life expectancy, and why men especially suffer from the suppression of these pro-social emotions.
