Want to live a long life? A study of 1,500 children born in 1910 revealed the secret of a long life: conscientious habits.

"Most people who live to an old age do so not because they have beaten cancer, heart disease, diabetes, or lung disease; rather, the long-lived have mostly avoided serious ailments altogether," according to Howard S. Friedman and Leslie R. Martin, in their recent book, "The Longevity Project."

"The best childhood personality predictor of longevity was conscientiousness--the qualities of a prudent, persistent, well organized person," according to the two professors (he at the University of California--Riverside, and she at La Sierra University). "Conscientiousness . . . also turned out to be the best personality predictor of long life when measured in adulthood."
