One component of type A behavior is hostility. A recent study of more than 3,000 people showed that while the distribution of different levels of hostility was about the same in men and women, the medical profiles of the two sexes differed. The more hostile men were more likely to suffer from heart problems than those who were less hostile, whereas women showed no such correlation. The more hostile women, however, had a higher incidence of diabetes. No telling yet why there is a difference, but it’s an interesting finding. I’m curious about the biochemistry involved, and also about how it got to be that way.
