Harvard University has conducted a fascinating
longitudinal study over 75 years of men in two very different cohorts –
268 were healthy college sophomores from the classes of 1939 – 1944
465 were disadvantaged non delinquent inner-city youths from Boston between 1940 – 1945
The goal of the study was to identify predictors of healthy aging.
The main conclusion is that “warmth of relationships throughout life has the greatest positive impact on ‘life satisfaction'”.
The study shows: “Happiness is love. Full stop.”
