Play is a real treasure of a popular science book. Based on Brown's work as a clinician and deep familiarity with the literature, it moves through the deep important of play to all animals, and especially human beings. Far from being frivolous, play and a playful attitude is associated with learning, with success, and with a longer and healthier life. Imaginative play, exuberant play, and play free from consequence or adult supervision, is what makes us human, and what makes life worth living.

Brown strays into pat self-help in places, and Boomer kid-shaming in others, but this book is everything I wanted to be Exuberance to be.
