Season 2, Episode 11: Aging

At the biological level, aging results from the impact of the accumulation of molecular and cellular damage over time. This leads to a gradual decrease in physical and mental capacity, a growing risk of disease and ultimately death. These changes are neither linear nor consistent, and they are only loosely associated with a person’s age in years. The diversity seen in older age is not random, it’s about your genetics, how you are able to live and how you choose to live.
