abstract="The increasing recognition of the morbidity and mortality produced by competitive body-contact sports leads to a reassessment of the benefits alleged to accrue to the participants. Although advocates continue to assert that participation improves both moral character and physical health, there is increasing evidence that for some players it reinforces aggression, exacts a severe toll in physical injury, and may produce a general response pattern that is dysfunctional in a modern industrialized society.<p />",
