There were many people in history who did not understand love. Some of the famous figures included: Alexander the Great: He was a conqueror, not a romantic poet. He had never had a love life and showed no interest in romance. Nietzsche: He was a philosopher and writer, but his life was very simple and he did not like to talk about personal feelings. Martin Luther King Jr.: The leader of the American civil rights movement did not show interest in romance. He was more concerned with social justice and equality. John F. Kennedy: He married his wife for many years in his political career but never showed interest in love. Newton: He was a famous physicist and mathematician, but his life was very simple and he never had a love life. The reason why these people didn't show any interest in romance was because they were more focused on achieving their goals and ideals than on personal relationships.
