"Fire runs through my body with the pain of loving you. Pain runs through my body with the fires of my love for you. Pain like a boil about to burst with my love for you, consumed by fire with my love for you. I remember what you said to me. I am thinking of your love for me. I am torn by your love for me. Pain and more pain — where are you going with my love? I am told you will go from here. I am told you will leave me here. My body is numb with grief. Remember what I said, my love. Goodbye, my love, goodbye."
— Helen Fisher in her lecture "The brain in love"
