We've all heard it before: a poison rises in your gut, your pulse quickens, your jaw tightens, and it feels as if you're about to explode like a pressure cooker. Since time immemorial, humans have strived to find ways—more or less successful—to channel anger: counting to ten before speaking, punching a pillow, yelling into the wind (or at the unfortunate person in front of us)... But, according to a study published in the journal Nature, the solution could be found in a practice as simple as it is ancient: write the thought that has angered us on a piece of paper, tear it up and throw it away.
