Originally published in 1987, this volume, and the working conference that preceded it, broke new ground in addressing the complex topic of aging, health, and behavior. Taking a bio-behavioral approach to a range of topics, contributors to this book advanced their disciplines. This volume as well as searching for important interfaces between behavior and health also added the dynamic aspect of aging. Cells, organ systems, and whole human beings all change as they move through life, linking health in varied and intricate ways to changes in behavior patterns, social structures, and cultural values and norms.
