Satisfaction: The Science of Finding True Fulfillment

Berns kicks off this thought-provoking exploration with a simple question, "What do humans want?" He challenges the belief that we are driven primarily to pursue pleasure and avoid pain. Rather, Berns finds that "satisfaction comes less from the attainment of a goal and more in what you must do to get there." With a series of experiments using cutting-edge MRI scanning technology, he sees that the interaction of dopamine, the hormone secreted in the brain in anticipation of pleasure, and cortisol, the chemical released when we are under stress, produces the feelings people associate with satisfaction. Berns, an associate professor of psychiatry and behavioral sciences at Emory, ventures into the physical world to prove his thesis, looking at bruised and reddened s&m enthusiasts and ultramarathoners collapsing after a 100-mile run. The author then brings his journey home, confronting issues in his own marriage and the sexual dissatisfaction that so often plagues long-term relationships. His conclusion is simple and compelling: people are wired for novel experience, and when we seek it out, we are satisfied. This will be a highly satisfying read for anyone interested in what gets us out of bed in the morning day after day. Agent, Susan Arellano . (Sept. 1)
