The same genes are responsible for good health and high IQ, suggested psychologists from the University of Vienna. The work was published in the journal Intelligence. Previously, scientists have recorded that the higher a person's IQ, the better his health. However, the reasons for this dependence have not been established. To close this gap, scientists analyzed data of 13-year research, which contained information on cognitive, physical and psychological state of 11 thousand volunteers older than 50 years. Analysis of the data confirmed that the higher a person's IQ, the better their health. However, no behavioral factors were found to influence this relationship. Lack of physical activity was the only variable that was associated with both IQ and health. According to the scientists, the relationship between intelligence and health may be explained by genes. It is likely that the same genes can affect health and IQ. Researchers plan to test this theory in future papers.
