The United Nations is celebrating the International Day of Happiness today and if you've ever wondered how to live a long, successful and happy life, Harvard researchers may just have your answer.
"The surprising finding is that our relationships and how happy we are in our relationships has a powerful influence on our health," Robert Waldinger, a psychiatrist and professor at Harvard Medical School, told The Harvard Gazette in 2017. "Taking care of your body is important, but tending to your relationships is a form of self-care too. That, I think, is the revelation."
The ongoing Harvard study is considered one of the world's longest studies of adult life, having started in 1938 during the Great Depression.
