If you could fit our culture of convenience into a petri dish, what would it look like? Movement Matters is a series of essays in which biomechanist Katy Bowman continues to explain the mechanics of a sedentary culture and the deep complexity of the phenomenon we call movement. By exposing convenience as a way of outsourcing movements, Katy's groundbreaking work in the relationship between movement and nature expands to models that have evolved from thinking of the body as a single structure to considering it to be a cluster of a trillion bodies, and how those trillion bodies are being loaded by our habitat and how we move to interact with it. From movement nutrients to forest school to the problems with investigating parts, our culturally conditioned preference to be sedentary is explored from many angles. Thought-provoking, inspiring, and always entertaining, Movement Matters is a collection of essays conducting a deep exploration of movement and its role in science, community, work, and social responsibility. Deftly deconstructing sedentary assumptions that underlie much of our research into human health, Bowman works to reclaim our space in and responsibility to nature and ourselves. With essays on foraging, the nearsightedness epidemic, and the limitations of a parts approach to health, Bowman's gaze is sweeping and incisive, always with the underlying message that moving is powerful and important, and perhaps the most joyful, freeing, and efficient form of activism there is.
