Aging refers to the gradual biological process of becoming older, characterized by a variety of physical, psychological, and social changes that can occur throughout a person’s life. Biologically, aging involves the accumulation of cellular and molecular damage, leading to a decline in the physiological functions of the body. This process may manifest in changes such as decreased cellular regeneration, reduced organ function, and increased susceptibility to diseases.
Psychologically, aging can affect cognition, emotional well-being, and social interactions, often resulting in shifts in life priorities and perspectives. In a broader societal context, aging relates to the demographic trends seen in populations, where a growing number of older adults can impact healthcare, economics, and social structures.
The study of aging encompasses various fields, including gerontology, which focuses on the aging process and the challenges and opportunities that come with it. Overall, aging is a complex, multifaceted phenomenon that is influenced by genetics, lifestyle, environment, and healthcare access.
