Want another reason to stay in school?

Here's a reason (from the Boston Globe) for getting a good education:

Life expectancy has been steadily rising for Americans, but better-educated people are adding years to their lives, while those with high school diplomas or less are falling further behind, according to a Harvard study in the current issue of Health Affairs. In 2000, life expectancy for someone with 12 years of education or less was nearly 75 - the same as a decade earlier. But for someone with more education, life expectancy had jumped from 80 to 81.6 years during the decade, according to an analysis of death certificates, Census population estimates, and national mortality data. Different rates of smoking accounted for much of the disparity.
