According to a study published online Aug. 16, 2010, in the journal Hypertension, individuals who tend to be quick to argue and compete tend to have thicker carotid arteries, which place them at higher risk for heart attack and stroke. Researchers found that people who were more agreeable tended to have thinner arterial walls. Characteristics of "antagonistic" people included being distrustful, skeptical, self-centered, and quick to express anger. But some experts disagree with the findings.
