Believe it or not, but it is true! The higher is your IQ the less you are susceptible to stress. It was found during a research that brainpower might play a vital role in keeping you away from stress and various other mental and psychological disorders. Moreover, researchers believe that people with higher IQ are less likely to develop post-traumatic stress disorder (PTSD), which may even include act of violence, life-threatening illness. The researchers gave vent to this idea when they examined IQ of some people and came to the conclusion that people with higher IQ were less prone to stress and anxiety in the later years of their lives. On the contrary, people with lower IQ were found more susceptible to stress and other mental and psychological disorders.
