The Harvard Study of Adult Development, led by Robert Waldinger, tracked World War II veterans for decades to identify predictors of longevity.
The finding
What the evidence shows
The Harvard Study of Adult Development did track many men who went on to serve in World War II, but it wasn't a study built around veterans. It began in 1938 following two separate groups, Harvard undergraduates and disadvantaged Boston youths, defined by their backgrounds rather than by military service.
