Named a Best Book of the Year by Npr and LitHubWinner of the 2021 Science in Society Journalism Book Prize. A fascinating and provocative new way of looking at the things we use and the spaces we inhabit, and a call to imagine a better-designed world for us all. Furniture and tools, kitchens and campuses and city streets nearly everything human beings make and use is assistive technology, meant to bridge the gap between body and world. Yet unless, or until, a misfit between our own body and the world is acute enough to be understood as disability, we may never stop to conside or reconsider the hidden assumptions on which our everyday environment is built. In a series of vivid stories drawn from the lived experience of disability and the ideas and innovations that have emerged from it from cyborg arms to customizable cardboard chairs to deaf architecture Sara Hendren invites us to rethink the things and settings we live with. What might assistance based on the body's stunning capacity for adaptation rather than a rigid insistence on normalcy look like. Can we foster interdependent, not just independent, living. How do we creatively engineer public spaces that allow us all to navigate our common terrain.
