Taking the Long View

No one becomes old overnight--although it sometimes feels as if we do. Aging is a long-term endeavor, and some researchers are finding that the process is best viewed through slow-motion studies

Abstract: In the past half-century, longitudinal studies have proven themselves to be powerful tools for research on aging and its attendant diseases. These projects track the health of a group of subjects for years, observing factors that might predict the incidence of age-related diseases or influence processes commonly associated with normal aging, such as fading eyesight and hearing loss. Huge investments in these expensive, big-team, delayed-gratification enterprises have paid off handsomely. They have revealed risk factors for heart disease, cancer, and Alzheimer's disease, among others, and in some cases they've forced experts to rethink dogma on how to avoid illness. This tour highlights the strengths, weaknesses, quirks, and likely futures of some of the most important longitudinal studies.
