You're an astronaut, and Gravity can be your staunchest ally.
Moshe Feldenkrais' seminal work "The Body and Mature Behavior" laid out the fundamental truths underpinning what would eventually come to be known as the Feldenkrais Method: anyone can learn to be nimble, light on their feet, and free from untoward emotional distress, if they can learn to manage gravity in their bodies.
This book explains some of Feldenkrais' revolutionary insights, expressing them within five simple, easy-to-understand lessons that anybody can perform -- so that you can enjoy greatly enhanced physical, mental, and emotional fitness in your own life.
