" The problem is that you can't tell an individual patient where she sits on the curve: Will she die in six months or sixty? I came to believe that it is irresponsible to be more precise than you can be accurate. Those apocryphal doctors who gave specific numbers ("The doctor told me I had six months to live"): Who were they, I wondered, & who taught them statistics? "
