Physical fitness: how to help older patients live stronger and longer. (1).

Most older Americans are not physically fit and do not exercise regularly. This is especially true of older women, who are weaker than men and become disabled and dependent in the later years at a much greater rate. Exercise can increase the body's metabolism and make it more efficient in burning calories. Physical fitness also makes respiration more efficient. Evidence suggests strongly that the physically fit live 2 to 3 years longer and have a better quality of life than sedentary individuals. Any time is the best time for a person of any age to start exercising. Exercise is movement--dancing, walking, lifting a weight, using the body. Older individuals tend to be willing to exercise if they are given appropriate recommendations and follow-up.
