The US government's National Institute on Aging (NIA) has
conducted an extremely detailed, long-term study of more than
1200 citizens of the city of Baltimore, Maryland who currently
range in age from their early 20's into their 90's. This is
a "longitudinal" study which means that the individual participants
are followed over decades, passing through full physical and
psychological examinations every two years. As a result, this
study can give us an idea of what happens to real people as
they age that a study at only one point in time could never
do. You can read more about the Baltimore
Longitudinal Study on Aging
at its website.

Research Findings" right here at this site. The report is
available as an Adobe Acrobat file and its ten pages are a
fascinating summary of research results on twenty subjects
as diverse as brain activity, personality changes, and the
effects of alcohol.
