Twenty-two variables were found to be significant predictors of longevity among 252 panelists in a 25-year longitudinal study of aging. The strongest independent predictors for men were health self-rating, work satisfaction, and performance intelligence; for women they were health satisfaction, past enjoyment of intercourse, and physical function rating. These predictors could constitute a combined difference in longevity of 16 years for men and 23 years for women.
