A groundbreaking book on the science of play, and its essential role in fuelling our intelligence and happiness throughout our lives.Weve all seen the happiness in the face of a child whos playing in the school yard. Or the blissful abandon of a golden retriever racing with glee across a lawn. This is the joy of play. By definition, play is purposeless and all-consuming. And, most important, its fun.As we become adults, taking time to play feels like a guilty pleasure a distraction from real work and life. But as Dr Stuart Brown illustrates, play is anything but trivial. It is a biological drive as integral to our health as sleep or nutrition, and the mechanism by which we become resilient, smart, and adaptable people. In fact, our ability to play throughout life is the single most important factor in determining our success and happiness.Dr Brown has spent his career studying animal behaviour and conducting more than 6000 play histories of humans from all walks of life from serial murderers to Nobel Prize winners. In Play, he provides a sweeping look at the latest breakthroughs in our understanding of play and its implications for our lives, including its role in child development and the way we parent; education and social policy; business innovation; productivity; and even the future of our society.A fascinating blend of cutting-edge neuroscience, biology, psychology, social science, and inspiring human stories of the transformative power of play, this book proves why play just might be the most important work we can ever do.
