Imagine what your life would be like if you could not experience emotion. What if you felt no joy at seeing a newborn baby and no pride upon receiving a long worked-for diploma? What if you felt no anger and no fear when you heard that a terrorist attack had occurred in your country? What if you felt no jealousy at seeing a boyfriend or girlfriend flirt with someone else at a party, and you felt no awe when standing on the rim of the Grand Canyon? What would your life be like then? Would we even call it human life? And could human life indeed exist if we felt no emotion?
