From The Shining’s Grady twins to the It’s Always Sunny’s McPoyle boys, twins tend to come with a universally creepy reputation, which can be a bummer to anyone who’s shared a womb. Now a study out of Denmark makes it seem like the haters are just jealous, because there’s 30 years of evidence that suggests twins live longer. (But in defense of the haters, that’s also kind of creepy.)
Scientists looked at data from over 2,900 same-sex twins obtained from the Danish Twin Registry between 1870 and 1900, so 100 percent of them are unavailable for horror movies because they’re dead now. But when they were alive, they found that identical twins lived longer than fraternal ones, and fraternal pairs outlived everyone else. More specifically, identical twins lived 4 to 5 years longer than the general danish population during that time period, which to be fair was the end of the 19th century. As for how twins hold up nowadays, there still needs to be more research done outside of Denmark in the 1800s. Until then, twins can feel free to hold this over everyone else’s heads.
The lead author of the research suspects that this longer lifespan is due to the bonds twins maintain throughout life, and potentially increased emotional and/or financial support as a result. Similar to the idea of the “marriage protection effect” the study dubbed this as the “twin protection effect.” But if it all comes down to relationships, than you technically don’t have to be a twin to reap the longevity benefits. The catch is that you have to be willing to form a bond with someone who doesn’t share your face.
