From Harvard Gazette:
Think about this the next time someone cuts you off in traffic or in a grocery store line: Anger can bring on a heart attack or stroke.
That’s the conclusion of several studies at Harvard Medical School and elsewhere. One study of 1,305 men with an average age of 62 revealed that the angriest men were three times more likely to develop heart disease than the most placid ones.
Angry older men, as stereotypes go, are most vulnerable. But excessive ire can take a toll at any age. Researchers at Johns Hopkins School of Medicine tracked 1,055 medical students for 36 years. Compared with cooler heads, the hotheads were six times more likely to suffer heart attacks by age 55 and three times more likely to develop any form of heart or blood vessel disease.
The conclusion is clear: Anger is bad for you at any age.
