The article reports on the findings two studies in Europe related to professional workers. First, a study of British workers conducted by the Finnish Institute of Occupational Health found that workers who felt they were being treated fairly by their supervisor had a much lower incidence of coronary heart disease, which is the number 1 killer in Western societies. Out of the 6,400 male civil servants polled, those who felt they were treated fairly had a 30 percent lower risk of heart disease than those who did not. Academic researchers in Scotland have come to the conclusion that women's ambition varies by height. The study shows that taller women are more ambitious and more likely to have their first child later in life. Researchers suggest that taller women usually have more testosterone, which could increase some male traits in them, such as assertiveness, competitiveness, and ambition.
