The Biology of Being Alive begins with the human body—what it is made of, how its cells stay alive, and how the systems of the body work together to support health.

The Biology of Longevity explores what helps the body function, adapt, repair, and remain healthy as we age. We look at the biological processes connected to aging and longevity and examine how everyday factors such as movement, nutrition, sleep, and the environment can influence those processes over time.
