Living conditions so improved that infant and childhood mortality were profoundly reduced and medical advances in the prevention and treatment of leading causes of death among adults, such as heart disease and cancer, further extended the lives of older individuals. As a result, in the course of a single cen- tury, the average life expectancy in developed countries nearly doubled. For the first time in human history, old age became a normative stage in life. Not only are individuals liv- ing longer on average, but populations have begun to age as a result of this increase in life expectancy along with a precipitous drop in fertility rates. Countries in the developed world are rapidly reaching the point where there will be more people over 60 than under 15. Thus, the status of older people holds ramifications for the functioning of entire societies. Even though the near-doubling of life expectancy was a spectacular achievement, there were not concurrent advances in our ability to alleviate the disabling conditions of later life. Nor were there sociological advances to create a world as responsive to the needs of very old people as to those of the very young. In order to realize the enormous potential of longer life, scientists must come to a more comprehensive understanding of human aging and the social, psychological, and biological factors that contribute to optimal outcomes. Along with the phenomenal advances in the genetic determinants of longevity and susceptibility to age-related diseases has come an awareness of the critical importance of environmental factors that modulate and even supersede genetic predispositions. This series provides a bal- anced perspective of the interacting factors that contribute to human aging. The Handbooks of Aging series, consisting of three separate volumes, the Handbook of the Biology of Aging, the Handbook of the Psychology of Aging, and the Handbook of Aging and the Social Sciences, is now in its seventh edition and has provided a foundation for an under- standing of the issues of aging that are relevant both to the individual and to societies at large. Because discoveries in these fields have been both rapid and broad, the series has played a uniquely important role for students and scientists. By synthesizing and updat- ing progress, they offer state-of-the-art reviews of the most recent advances. By continually featuring new topics and involving new authors, they have pushed innovation and fostered new ideas. With the explosion of information and research on aging in recent decades, there has been a concomitant increase in the number of college and university courses and programs focused on aging and longevity. The Handbook of Aging series has provided knowl- edge bases for instruction in these continually changing fields. Indeed, the Handbooks are resources for teachers and students alike, providing informa- tion for didactics and inspiration for further research. Given the breadth and depth of the material covered, they serve as both a source of the most current information and as an overview of the various fields. One of the greatest strengths of the chapters in the Handbooks is the synthesis afforded by authors who are at the forefront of research and thus provide expert perspectives on the issues that currently define and challenge each field. The interdis- ciplinary nature of aging research is exemplified by the overlap in concepts in chapters rang- ing from basic biology to sociology. We express our deepest thanks to the editors of the individual volumes for their incred- ible dedication and contributions. It is their efforts to which the excellence of the products xi Foreword is largely credited. We thank Drs. Edward J. Masoro and Steven N. Austad, editors of the Handbook of the Biology of Aging; Drs. K. Warner Schaie and Sherry L. Willis, editors of the Handbook of the Psychology of Aging; and Drs. Robert H. Binstock and Linda K. George, editors of the Handbook of Aging and the Social Sciences. We would also like to express our appre- ciation to Nikki Levy, our publisher at Elsevier, whose profound interest and dedication has facilitated the publication of the Handbooks through their many editions. And, finally, we extend our deepest gratitude to James Birren for establishing and shepherding the series through the first six editions. Thomas A. Rando, Laura L.
