Several years ago some medical practitioners had a hard time predicting which types of people would experience cardiovascular disease. In fact, they knew that high blood pressure, overweight, and inactivity would increase cardiovascular risks. However, even the combination of these factors was not enough for them to make an accurate prediction. So, they had to do pretty deep researches. Then, they’ve found a relationship between chronic medical morbidity and personality characteristics (Burger, 2006).
