Aging is the biological process of growing older and showing the effects of increasing age. A person's birthday is often an important event from which their age is measured, usually counted in years for adults and months for infants. Roughly 100,000 people worldwide die each day of age-related causes. The rate of aging is highly dependent upon genetics, lifestyle, and environmental factors.
Aging in humans often refers to a multidimensional process of physical, psychological, and social change. Some dimensions of aging grow and expand over time, while others decline. For example, physical reaction time may slow with age, while knowledge and wisdom may expand. Research shows that even late in life potential exists for physical, mental, and social growth and development. Aging is an important part of all human societies reflecting the biological changes that occur, but also reflecting cultural and societal conventions.
