For anyone teased in school for being a ‘know-it-all,’ you may be getting the last laugh—literally. A new study shows that smarter people live longer likely due to their genetics. After analyzing 7,000 sets of twins at different ages and different genetic backgrounds, researchers found that there was a small connection between their length of life and IQ levels. One theory is that having more intelligence leads to better jobs, higher socioeconomic status and greater access to the crème de la crème of health resources as well as the ability to make more informed choices about their health. Regardless of what this study says, taking initiative and being smart about your well being—whether it comes naturally for you or requires some extra research—will always be a wise choice. Do you think there’s some truth to this intelligence/longevity link? Sound off in the comments!
