does education help us live longer?

Well....maybe. Some of us.

This study found no racial differences in leukocyte telomere length (which is associated with longevity) until they factored in education. Consistent with previous studies, Blacks had longer telomeres than Whites. An examination of the interaction of race and education showed that Blacks with more than a high school education had significantly longer telomeres than any other group (Blacks with less than high school education and Whites with any level of education). 

Really fascinating study.
