S. Jay Olshansky and Bruce A. Carnes provide a comprehensive account of the real science of aging, from a historical overview of religious and philosophical thinking about aging and death, to the biology behind the changes we see in the mirror, to the promising but frightening future of genetic engineering. The Quest for Immortality demystifies the complex language and concepts of science, explains how to distinguish real science from media hype in order to help readers make informed health decisions, and offers a powerfully optimistic vision of aging and health in the twenty-first century.
