HOSTILE MIND, HOSTILE HEART The more cynical and mistrustful your personality, the more likely you are to have heart disease. This, according to a new study, could account for the disproportionate number of blacks afflicted with it. The study found that blacks generally score higher on hostility tests, and the people who score highest on hostility test are most likely to have systolic blood pressure, which leads to heart disease. The implication that black people are hostile is making my blood pressure rise (ha!). But, whatever. This is one very good reason for people of all races to try to relax more. [USAT]
