For much of our lives, we describe ourselves as being in various emotional states such as happy, sad, anxious, or in love. Often we notice that these emotions produce physical symptoms—for example, your heart racing the day before an important exam, or the physical pain you feel when you see the person you are in love with with someone else. Why do we experience these physical symptoms? What factors influence the formation and regulation of our emotions? The answer is not as simple as it may see
