This text offers a readable and friendly presentation of the important methods, findings, and theories of human aging, while actively involving the reader in meaningful exercises and critical thinking. Readers are repeatedly challenged to apply information in the text to the older adults in their own lives. Specifically, suggestions for enhancing the lives of their older relatives are offered and encouraged. These include guidelines for discussions they might have regarding social, emotional, and environmental changes as well encouraging intellectual and social interaction. While presenting the latest in research findings, the authors have also strived to keep research interesting for readers who may not see themselves as researchers.
