What is aging? That’s the question the National Institutes of Health (NIH) sought to answer in 1958 when it launched the Baltimore Longitudinal Study of Aging (BLSA)—now the world’s longest-running study of human aging.
Some 3,200 men and women have played a critical role in advancing our understanding of what it means to get older. And these particular volunteers made a lifelong commitment to participate in the research. In over six decades of work, BLSA researchers say they are certain of just two things: Aging is not synonymous with disease. And we all age differently.
