Note: Basic regressions include controls for age and gender. Economic measures include family size, family income, family income missing, major activity, marital status, and region. Family background measures include self reported health status at age 16, whether born in the US, whether speak English at home, dad born in the US, dad's employment status at age 16, dad's education, dummy for dad alive at time of survey and dad's health status if alive, head of the household when was 16, mom's employment status at age 16, mom's education, mom alive at time of survey and mom health status if alive, whether family was on welfare while growing up, whether family was better off than other while growing up. Personality measures include a depression scale, a generalized anxiety scale, a scale on sense of control, a positive affect scale and a negative affect scale and dummy variables whenever each scale is missing. Social integration measures include a scale of social integration, the scale of social contribution, a scale on positive relations with spouse, a scale on negative relations with spouse, a scale of positive relations with friends, a scale on negative relations with friends, and dummy variables whenever each scale is missing. Effort put into health: individuals were asked to rate from 0 to 10 "How much thought and effort do you put into your health these days?", were 10 is the highest. Work hard to stay healthy: individuals were asked how strongly they agreed with the statement "I work hard at trying to stay healthy" & 1 is coded as strongly agree. MIDUS weights are used in all regressions and in calculating means. Unweighted regressions use the methodology of Kling et al. (2007). Mortality weights assume no difference in drinking.
