Primary aging derives from mechanisms inherent to our biology, such as the damaging mechanisms listed in the Strategies for Engineered Negligible Senescence (SENS) view of aging. Secondary aging derives from lifestyle choices (such as diet and exercise) and environmental exposures (such as particulate air pollution or persistent viral infections), harmful factors that can interact with the mechanisms of primary aging to accelerate the path to loss of function, age-related disease, and mortality. Epidemiological studies suggest that many people are losing at least a few years of life to poor choices, poor luck, or poor li…
