Aging

Aging refers to the process of becoming older, characterized by a gradual decline in physical and psychological functions, changes in appearance, and an increased risk of age-related diseases. It encompasses biological, social, and psychological aspects, influencing an individual’s health, cognition, and social interactions over time. In biological terms, aging involves cellular and molecular changes, such as telomere shortening, accumulation of cellular damage, and altered metabolic processes. Socially and psychologically, aging can impact relationships, roles in society, and mental health. The study of aging is known as gerontology, which examines the effects of aging and ways to improve the quality of life for older adults.
