A neuroanthropologist maps out a revolutionary new practice-Hedonic Engineering-that combines the best of neuroscience and optimal psychology. It's an intensive program of breathing, movement, and sexuality that mends trauma, heightens inspiration and tightens connections-helping us wake up, grow up, and show up for a world that needs us all.

This is a book about a big idea. And the idea is this: Slowly over the past few decades, and now suddenly, all at once, we're suffering from a collapse in Meaning. Fundamentalism and nihilism are filling that vacuum, with consequences that affect us all. In a world that needs us at our best, diseases of despair, tribalism, and disaster fatigue are leaving us at our worst.
