It's a big expense of both time and money, but a graduate degree apparently leads to life with slightly lower blood pressure, especially for women. Science Daily reports that researchers at Brown University, using data from the Framingham Heart Study, found that women who completed 17 years of schooling or more had systolic blood pressure on average 3.26 (mmHg) lower than women who did not finish high school. Women who went to college but did not pursue graduate studies had a 2 mmHg benefit compared to less educated women. For men, going to graduate school versus not finishing high school made a 2.26 mmHg difference, with a lesser benefit for going to college. For women, the most educated group retained a 2.53 mmHg benefit over the least educated. In men, the difference was much less, only 0.34 mmHg.
