Video: 100 Years Old and Counting: Psychological and Biological Factors

This entertaining video clip introduces the viewer to Ray and Elva, two centenarians who exemplify recent research studies aimed at uncovering the secrets of longevity.
Because centenarians tend to have family members who are also long-lived, scientists have examined their DNA in hopes of identifying genes that may contribute to their longevity. These linkage analysis studies may lead to the development of life-extending medications. Large-scale studies of centenarians also point to the importance of factors in the psychological and social domains of health. Ray thrives on his curiosity as a scientist, while Elva enjoys painting and weekly outings with her friends.
