Through a video call that lasted for more than 5 continuous hours, and after reviewing the entire content of the book and the scientific opinions it contained, I promised my friend Dr. Ahmed Kamal, the psychiatrist, that the next question would be the last: “Why do we love?” He received my question with his usual laugh and replied: “This is the million dollar question, as they say here in America!” The question that has no answer. I asked him: “It really has no answer?” He replied: “It has no fixed answer that works for all people. The beauty of love is that it is like a fingerprint; it differs from one person to another. Why do we love? We love for millions of reasons that we don’t need to explain to anyone and that don’t necessarily convince anyone else. Who do we love? All those around us feel that we are 1 + 1 = 1. How do we love? When we listen more to the person in front of us and give them the same thing we ask of them. When do we love? When we fall in love with an action despite its simplicity, and are not tempted by words despite their beauty, actions are overwhelming and are the only language spoken and heard by those who truly love. Why do we love? The answer to your question is in your book, "This is Why We Love," a journey of research into stories and psychological readings about love, its causes and its people.
