HEAVY BURDEN

When you keep a secret, it’s often said that you “carry a heavy burden” or you have “a weight on your shoulders.” Those are not just metaphors. Columbia University research reveals that people who keep something under wraps find everyday tasks, like lugging groceries upstairs, physically harder. Keeping a secret also ups your stress level, hurts your memory, and messes up your metabolism.
