Why do some people live so long? Is it nature? Nurture? A complex mix of both? Thomas Perls, a [...]School of Medicine associate professor of medicine and geriatrics, is hoping to find the answer. In 1994, he launched the New England Centenarian Study and started enrolling long-lived individuals from greater Boston. His team hopes that whatever nature-nurture mix is protecting centenarians could one day be harnessed for drug development, gene therapy, and behavioral interventions to keep the rest of us healthier longer, even if we don't live to 100. Listen to 96 year-old Agnes Buckley talk about how she stays healthy.
