We all hear of research studies that have been running for years. These are called longitudinal studies as against cross-sectional studies, which examine certain issue at a specific point of time. The longitudinal studies investigate specific issues over a long period of time. But are you aware of a study, which has been running for over 75 years? This is a Study of Adult Development run by Harvard Medical School. The goal of the study is to identify predictors of healthy aging and it attempts to answer the question, what makes a good life? Dr. Robert J. Waldinger, the current director of the study, has shared the findings of this study in a TED talk recorded in Nov 2015. Watched for over 25 million times, this talk shares the lessons from the longest study on happiness.
