Sadness seemingly comes out of nowhere sometimes: a song, a photo, a movie scene, a memory, and there it is. Your heart seems heavy. Tears well up in your eyes. What is happening in the brain when we feel sad? We delve into this complex emotion, and explore how we experience it, and how we deal with it. From tears shed at the gym after a serious workout, to crying in public, and sad songs that help us cope with tough times.
