Future Pundit makes the case that being smart means living longer.
The inequalities in all cause death rates between Americans with less than high school education and college graduates increased rapidly from 1993 to 2001 due to both significant decreases in mortality from all causes, heart disease, cancer, stroke, and other conditions in the most educated and lack of change or increases among the least educated. For white women, the all cause death rate increased significantly by 3.2 percent per year in the least educated and by 0.7 percent per year in high school graduates. The rate ratio (RR) comparing the least versus most educated increased from 2.9 (95% CI, 2.8–3.1) in 1993 to 4.4 (4.1–4.6) in 2001 among white men, from 2.1 (1.8–2.5) to 3.4 (2.9–3–9) in black men, and from 2.6 (2.4–2.7) to 3.8 (3.6–4.0) in white women.
While there are some differences between intelligence levels and levels of formal education, the two factors usually tend to hold hands and skip to the front of life. Those who cogitate more often and crack the books more often also tend to be more aware of factors that influence mortality and the current treatments and preventative steps available.
Audacious Epigone offers some factors that influence longevity and strongly notes that the dominating factor in long life is IQ. I wonder what 127 gets me?
