If I were a magician, I would do anything that would not have orphans anywhere in the world. All children will necessarily have a mom and dad. Families will be only strong, loving and friendly. Parents will never divorce. I would like to see our grandparents live longer, they have much to learn and very much want to stay with them longer. Taking advantage of my magician's power, I would try to arrange everything so that no one would like to fight. After all, living on Earth is so interesting and without wars. People would not become enemies, share lands, minerals and political power. They would just respect themselves and others.
