There are more than three million Americans over the age of 84. That number is expected to quadruple by the year 2040, when there will be more than 12 million people in that age group. The population age 85 and older is the fastest growing age group in the United States. Research has found that, except for the changes that can result from Alzheimer's disease and other forms of dementia, personality is one of the few constants of life. That is you are likely to age as much a you've lived.
Most older people can and do lead an active, satisfying life.
In later life, it's the quality of sleep that declines, not total sleep time. Researchers have found that sleep tends to become more fragmented as people age. A number of reports suggest that older people tend to take more naps than younger people. Most older people live close to their children and see them often. Many live with their spouses.
