"Aging is one of life's mysterious phenomenon. It is a complicated process involving all of the many subtle changes that occur in our body with the passage of time. Aging happens to us all but in different ways and at different rates. As a result of better medical care, improved diets and more emphasis on regular exercise participation, aging is no longer necessarily a stage to be dreaded. Today, people are living longer and enjoying better health than in previous generations (Spence, 1989)." Here, I will briefly discuss the biological and physiological changes which generally occur throughout the aging process. Keep in mind that some changes that are noticeable in older people may not be so much a result of aging as a result of the human body exposed to environmental factors such as nicotine smoke and air pollution over a period of many years.
