Baltimore Longitudinal Study of Aging (BLSA)

"The National Institute on Aging’s (NIA) Baltimore Longitudinal Study of Aging (BLSA) is America's longest-running scientific study of human aging. It began in 1958, when gerontology—the study of aging—was still very much in its infancy. Today, the BLSA is world-renowned, having generated thousands of scientific papers and made major contributions to our understanding of what it means to get older."
