Blazing a path to very old age: "Dr. Robert Butler, a longevity expert at Mount Sinai School of Medicine. Besides the Leisure World Cohort Study, other large, ongoing longevity studies in the United States include:
The Baltimore Longitudinal Study of Aging: This is the longest-running study of human aging in the United States, begun in 1958 with just a small group of male participants. The study is now following more than 1,400 men and women, ranging in age from 20 to 90 and older. So far, the study has found that older people cope more effectively with stress than young adults and that personality seems to stabilize after age 30.
The New England Centenarian Study: This research project, begun in 1994, currently involves 1,500 people, including centenarians, their children and siblings. The study has so far determined that Alzheimer's disease is not inevitable and that at least 50% of centenarians have first-degree relatives who also achieve very old age.
Exceptional Longevity Family Study: This is a new study funded by the National Institute on Aging that will collect health and genetic information from more than 3,000 long-lived volunteers in the United States and Europe and their descendants. The study will look for genetic links to the major diseases as well as examine the influence of personal health habits."
