Clinicians have long suspected that retirement is detrimental to the health of some patients. Now, investigators at Harvard Medical School's Channing Laboratory in Boston suggest that it may lead to fatal coronary heart disease.
Charles H. Hennekens, MD, and associates stumbled on this finding in the course of a study originally designed to test the hypothesis that coffee consumption is a risk factor for coronary heart disease.

All of the men had died of coronary heart disease within 24 hours after symptoms of it developed. They were matched by age (within one decade) and neighborhood of residence to an equal number of living control subjects chosen through systematic household
