A man stood looking through the window on the sixth floor of an office building. Suddenly, he was overcome by an impulse. He opened the window and leapt through it. It was a sheer drop outside the building to the ground. He did not use a parachute or land in water or any kind of special soft surface.Yet the man was completely unhurt when he landed. How could that be?
