A study out of Duke University has found that men who are hostile,depressed, and angry aren't just lousy company; they're also morelikely to get sick on you down the road.
According to the research, published in the August edition ofBrain, Behavior, and Immunity, such men develop higherlevels of C3, an immune system protein that reflects inflammation. Higher levels of C3 are associated with an increased risk of heartdisease, abnormal heart rhythms, and type 2 diabetes.
The researchers tested 313 men, first by assessing their feelings ofhostility, anger, and depression in 1985 and then by measuringlevels of inflammatory markers in their blood over a ten-year periodbetween 1992 and 2002. Those who'd had the highest level ofhostility and anger showed a 7.1 percent increase in C3 over thedecade of the study. Those with low levels of the same attitudes hadno change in C3 over the ten-year period.
It appears that the old adage "Don't sweat the small stuff" isn'tonly good for your interpersonal life; it just might keep that lifegoing for awhile longer as well.
