Why the Process of Aging Is Most Likely the Result of Cellular Damage
Cells accumulate DNA damage over time from metabolic byproducts, UV radiation, and oxidative stress. This damage impairs tissue function and is considered a primary driver of aging.
Genetic and Lifestyle Factors That Influence Aging
Genes regulate repair systems and inflammation, which affect how quickly people age. Lifestyle habits such as diet, sleep, and physical activity also shape the pace of age-related changes.
Key Research on the Biology of Aging
Major studies link aging to telomere shortening, mitochondrial decline, and altered cell communication. Researchers continue to map these mechanisms to better understand age-related disease risk.
