Book excerpt: As the field of aging and gerontology grows worldwide, this exciting guide introduces students to key issues and concepts. It covers topics related to the phenomena of advancing aging, including how older age has been defined historically, cultural myths related to advanced age, health and function in later life, how older age is financed throughout the world, and other key questions. Taking a multiple-perspective approach (including humanities, social and behavioral sciences and policy studies), the book's features include further reading for each chapter, a glossary of key terms, and tables that provide easy reference points.
