On Thanksgiving Day in 1987 I was barely able to walk into the hospital emergency room. My fever was 105 F. and rising. After an exam and a lung x-ray I was admitted to the hospital. The diagnosis was viral pneumonia, which is usually brought on by stress, and which has a long recovery period. Within the past year or so I had experienced a series of very stressful circumstances, including the death of my father. And, during these stressful events, I also had maintained a full-time job.
