This new edition reflects the continued changes in the way we age. The fourth edition has been updated to include emerging issues in aging. These include the prevalence of HIV/AIDs in later life, current research on mental potential in old age, the creation of age-friendly cities, and new options for end-of-life care. Each chapter begins with a set of learning objectives to guide students in their reading, and concludes with a list of main points, questions for discussion or study, suggested readings, and relevant web sites to consult. Each chapter also includes up-to-date charts and graphs as well as key terms to help students understand the issues presented. Break out boxes reveal the human side of aging through the stories of individuals in real life and in the media.
