The times sure have changed...I was at the hospital today. I should begin by mentioning I worked in a hospital 30 years ago. In those days, I remember only a couple "codes" for the intercom--Code red for a fire, code blue for a cardiac arrest. Nowadays, they have a code gray for a disaster (not specified what type of disaster, leading one to wonder); code pink for child abduction; code yellow for a bomb; code red for a cardiac arrest and code blue for something ambiguously dangerous...I forget now what word they used--let's just call it a really bad event like a terrorist attack or something. All indicating the world's become a dangerous place.
