Age Later: Health Span, Life Span, and the New Science of Longevity

Drawing on decades of research, Dr. Nir Barzilai examines why some people remain healthy and active well into their nineties. The book translates lab discoveries about the biology of aging into a clearer picture of how resistance to common age-related diseases develops.

Using studies of long-lived volunteers, the author maps biological factors linked to lower risk of diabetes, cancer, heart disease and cognitive decline. The narrative connects scientific findings to practical ideas for protecting health span rather than treating decline after it begins.

Readers will come away with a grounded understanding of current longevity science, what distinguishes so-called SuperAgers, and the research directions that aim to delay or prevent multiple age-related illnesses.
