Almost all medical professionals have seen what we call "futile care" being performed on people. What it buys is misery we would not inflict on a terrorist. I cannot count the number of times fellow physicians have told me, in words that vary only slightly, "Promise me if you find me like this that you'll kill me." They mean it. How has it come to this—that doctors administer so much care that they wouldn’t want for themselves? The simple, or not-so-simple, answer is this: patients, doctors, and the system.
