Methuselah lived to 969 years old, according to the Bible. In our recent age, Jeanne Calmet holds the title as the oldest person who ever lived. She lived to be 122 years and 164 days old. There’s a woman in Japan, Kane Tanaka, who is currently 118. Jiroemon Kimuri, also from Japan, is the oldest man of all-time, living to 116 years and 54 days. How did they do it? How do some people avoid the deterioration and weakness that plagues many of their peers decades early? Is it luck, or something else? Is it possible to grow older without getting sicker? Could a 90-year-old not look a day over 50?

In Age Later, Dr. Nir Barzilai, a pioneer in aging research, looks both at the four age-related diseases that take most of us (diabetes, cancer, heart disease, and Alzheimer’s) and at SuperAgers (people who have maintained active lives well into their 90s who’ve never experienced any of those diseases). What can we learn from these subjects, who have not only reached a ripe old age, but have further ripened the older they get? Dr. Barzilai reveals the secrets of these SuperAgers and the scientific discoveries so that we can mimic some of their natural resistance to the aging process. This isn’t saying, we’ll live to 969, but, for all of us, there’s still plenty of life yet to live.

Dr. Nir Barzilai is the founding Director of the Institute for Aging Research at Albert Einstein College of Medicine and the Nathan Shock Center for Excellence in the Basic Biology of Aging and the Einstein Glenn Center for the Biology of Human Aging. He is also the Scientific Director of the American Federation for Aging Research (AFAR).
