Over the years, there’s been a growing consensus that suggests being happy is correlated with living a long life. Well, you can wipe that smile off your face because a massive study published in The Lancent makes it clear that no such correlation exists. So what about all those studies suggesting that stress and joylessness hastened death’s arrival? According the new study’s co-author: “In our view, the previous studies haven’t been well done. All that’s going on is ill health actually was causing unhappiness and stress.” In other words, your unhappiness is going to last longer than you thought.
