Probably the easiest form of exercise we can all participate in is walking. A recent study by the Journal of the American Geriatrics Society stated that older people risk problems in the future with walking and mobility if they don't exercise now.

Through annual exams and telephone interviews, researchers discovered that mobility was maintained in older persons who exercised and had an active lifestyle.
