What is the aging process in humans?
Aging is a gradual, continuous process of natural change that begins in early adulthood. During early middle age, many bodily functions begin to gradually decline. People do not become old or elderly at any specific age. Traditionally, age 65 has been designated as the beginning of old age.

What are the processes of aging?
Aging is associated with changes in dynamic biological, physiological, environmental, psychological, behavioral, and social processes. Some age-related changes are benign, such as graying hair.
What are the factors that influence the aging process?
These influences include heredity, environment, culture, diet, exercise and leisure, past illnesses, and many other factors. Unlike the changes of adolescence, which are predictable to within a few years, each person ages at a unique rate. Some systems begin aging as early as age 30. Other aging processes are not common until much later in life.
How does the aging process affect different organs?
Aging is a complex process that varies as to how it affects different people and even different organs. Most gerontologists (people who study aging) feel that aging is due to the interaction of many lifelong influences. These influences include heredity, environment, culture, diet, exercise and leisure, past illnesses, and many other factors.
What are the most common signs of skin aging?
Among the most common signs of skin aging are as follows: Dark spots. Also known as age spots and sun spots are caused by hyperpigmentation due to sun damage. Sagging skin.

What do scientists think is the cause of aging?
Over the course of history, hundreds of theories about human aging have been proposed. Today, most scientists think that aging is caused by a complex interplay of different factors, including genetics, programmed physiological changes to our cells, and behavioral and environmental influences. Much of this process is unavoidable.
Is there any way to stop the aging process?
Here’s what you need to know: Although we can’t (yet) stop the physical process of growing older, scientists have found many ways to minimize the effects of aging.
