The world’s fifth-richest man sits alone in a rare moment of tranquility. Who is he? What is he thinking? Why is he here? Let me ask from him. He says about his love of the desert. “Sometimes I stay and sit alone there for one or two or three hours. I really feel serenity at home in the middle of the desert with no lights, only the light of the fire. I feel very much comfortable in the desert. I am a desert man.
