By 2030, the number of Americans age 65 and over is projected to reach some 71.5 million people, with nearly 10 million of them 85 and older. However, many seniors today report better health, greater wealth, and higher levels of education than elders in past decades.
Science is paying a lot of attention to the well-being of people in their later years. One area of concern is cognitive function, and the effects of dementia and Alzheimer’s disease. Physical health is another important area of concern for an aging population; keeping the body moving and healthy helps to ensure the quality of a long life.
More elderly workers aren't retiring, but staying employed and finding ways to contribute. Additionally, surveys find that more young people are turning to elders for advice and wisdom in a range of domains.
