Do you plan, calculate and worry some about the future? A study begun in 1921 by psychologists at the University of California, Riverside, shows that if you do, you’ll probably live longer.

The researchers found that people who are detail-oriented, responsible, organized, and more satisfied with their work live longer than those who aren’t. Study leaders say they have “high conscientiousness scores.”
Those with low conscientiousness scores tended to be less prudent in their health habits and more likely to smoke or consume excessive amounts of alcohol. They also had less stable personal relationships and less satisfying work lives.

The study was reported in Bottom Line Personal.
