Aging

Aging is the biological process of growing older, characterized by a gradual decline in physical and mental functions over time. It encompasses a range of changes in an organism’s body and mind, including slower metabolism, decreased cellular repair and regeneration, and alterations in hormonal levels. Aging can affect various systems, leading to increased vulnerability to diseases, reduced resilience, and overall diminished functioning. While aging is a natural part of life, it can also be influenced by genetic, environmental, and lifestyle factors. The study of aging encompasses fields such as biology, medicine, and sociology, as it examines not only the physiological changes but also the psychological and social implications of growing old.
