Life in a modern developed society has become too comfortable. This book's author, Michael Easter, theorized that living a life that is not challenging enough is actually the root cause of many of our most pressing physical and mental health problems, and set out on a journey through extreme conditions to explore the wild within. This book lays out a plan for harnessing the power discomfort that will greatly improve our health and happiness and perhaps even help us understand what it means to be human.
