2020 marks the 82nd year that researchers at Harvard University began following 724 college age men as part of the longest running study in history on human development. Their objective? To determine what factors lead to healthy and happy lives. Key results suggest that happiness and health do not result from fame and fortune. Instead, as the Director of the Harvard Study of Adult Development Robert Waldinger put it, the clearest message to emerge is, "Good relationships keep us happier and healthier. Period." Close relationships ... are better predictors of long and happy lives than social class, IQ, or even genes. Research from University College London found that people with a greater sense of purpose in life lived longer than those with the lowest sense of purpose. A study conducted with the elderly showed those who helped others lived longer lives. Researchers from Norway found that women who rated high for humor had a 48 percent lower risk of death from all causes. Research from University College London showed people who felt younger had a lower death rate than those who felt their own age or older. A Harvard study found the most optimistic people had a 16 percent lower risk of death from cancer, a 38 percent lower risk of death from heart disease and respiratory disease, and a 39 percent lower risk of dying from stroke. Research from UC Berkeley shows that experiencing awe can actually impact health by reducing inflammation and lowering the risk of diabetes, heart disease, and Alzheimer's.
