You scored your boss XX out of a possible 20 points, or a grade of XX%. Believe it or not, the five questions you just answered reveal not just the quality of your boss as a leader, but also reveal your risk of heart disease (which is the most common cause of death in Western countries).

In 2008 the journal Occupational and Environmental Medicine published a study titled, Managerial Leadership and Ischaemic Heart Disease. Researchers asked 3,122 men to rate their bosses using a ten question survey (the five questions above were the ones found to be most predictive). They then tracked the men for the next ten years to see which ones wound up hospitalized for heart attack, stroke or other cardiovascular problem. The study found that men who worked for effective leaders were about one third to half as likely to be hospitalized from heart disease, or to put it another way, working for a bad boss seems makes you 50% more likely to suffer a heart attack or related ailment.

If your boss has a rating over 75% she or he is doing a pretty good job on these five measures, and you’re likely not experiencing any boss-related health effects. If you rated your boss between 50% and 80% they have a mixed scorecard and you may be experiencing stress or dis-engagement that could increase your risk of cardiovascular events. If you scored your boss at 50% or less, you may have a much higher incidence of hospitalization or death from cardiovascular disease.
