'It seems everyone wants to live longer and longer, but Alstott, Gluck, and Rusyn are among the brave few willingly to peer into the near-term future and confront the social, economic, legal, and other problems created by centenarian societies. This book begins the absolutely invaluable task of delineating potential solutions to these problems. It will serve as the guidebook for all future work to create livable and just centenarian societies. Inevitably all of us-who will live long- will have to engage with its proposals.' Ezekiel J. Emanuel, Levy University Professor, Perelman School of Medicine and The Wharton School, University of Pennsylvania
