While researchers have long been piecing together all the ways chronic stress undermines our health, a new study confirmed what we suspected all along: stress really does age us. Facing a number of centenarians, we are probably wondering: what happened to those who didn’t perceive their lives as stressful? Stress didn’t age them nearly as much? But in fact, they lived through the Great Depression and World Wars I and II, not to mention the usual array of deaths of loved ones, job losses, and even divorces. So they endured a great deal of stress. The key to this matter isn’t the amount of stress but how we manage it. If we can treat stress like water off a duck’s back, we don’t seem to internalize it and just let it go, we should have a good and long life.
