In the past century, average life expectancies have nearly doubled, and today, for the first time in human history, many people have a realistic chance of living to eighty or beyond. Physician Mark Williams discusses the advances that medical science has made in the field of aging and the steps that people may take to enhance their lives as they age. Through his own observations and by use of medical research, Williams offers advice to help aging readers and those who care for them enjoy personal growth and approach aging with optimism and even joy. Refuting the perspective of aging that insists that personal, social, economic, and health care declines are persistent and inevitable, he takes a more holistic approach, revealing the multiple facets of old age.
