;In the 1992 book Intensive Care, by Dr. Robert Zussman, a professor of sociology at the University of Massachusetts, an I.C.U. intern reports a dream. In it, he finds penguins in a basement. The birds need to be in a cold environment or they will die, so to save one, he takes it, puts it into a blender with some ice and turns the blender on. The penguin is suddenly floating in a slushy pool of blood. The intern wakes up. The dream’s interpretation is clear enough: in the I.C.U., sometimes the cure is worse than the disease.
