Critically Ill

One evening a critically ill man was admitted to the coronary-care unit.
Time was of the essence. As he was wheeled in and placed in
bed, the scene became frenzied. Nurses rushed to get the patient
monitored, do a fast physical assessment, obtain pertinent
information and prepare equipment.

In the middle of this commotion, a doctor called out, "Does anyone know the
age of this patient?"

Just as one nurse was about to look at his admission sheet to check, a
voice from the bed offered: "I know. I'm 75."
