If you have too much self-confidence, it might hurt your health. Each person’s level of self-confidence is different, and it influences our behaviors, actions, and decisions. It also plays a role in risk-taking, drinking alcohol, and more. In this new study, researchers at the University of Vienna collected data from over 80,000 European adults aged 50 and older. They found that people who overestimate their health see doctors 17 percent less often than people who more accurately perceive their health. A similar trend was found regarding seeing dentists for regular checkups. Seeing your doctor less could allow medical conditions to advance undetected and untreated. On the other hand, people who underestimate their health saw doctors 21 percent more frequently.
