Law and the 100-Year Life addresses the growing trend of Americans living longer and healthier lives, with many reaching the age of 100. An aging nation presents new challenges for society, which must be reimagined to accommodate longer and more varied careers, multiple marriages, and defining moments of education. This volume explores the possibility of a 'third demographic dividend', a new period of productivity following middle age, and the potential for law and policy to support or divide aging citizens. Leading scholars across various fields come together to explore topics related to aging, such as health law and trusts and estates, as well as less obvious but equally important areas like housing, criminal justice, and education.
