By this point in your life, you've probably heard, clicked on, and shared tons of tips on how to maintain a happy relationship. But new neurological research shows there may be one very important martial skill you haven't considered yet.
Researchers at the Rotman Research Institute in Toronto and at the University of Toronto scanned the brains of women who'd been married for an average of 40 years. Through a series of tests, they found that these women, who had been married for decades, paid very close attention to their husband's happiness.
New York Magazine's Science of Us put together a video that explains how this experiment worked and what it means for you.
"One of the keys to a long-lasting relationship is the ability to notice when your partner is elated even if you're not feeling particularly happy at the moment," the video says.
So, next time your significant other has a victory on a day you're feeling crappy, try to celebrate the win.
