Lengthy sick bed confinements can mean hours of boredom. When the hours drag on tediously, the mind and emotions do things which doctors agree may hinder convalescence. Anyone caring for the sick knows that enforced idleness can make the patient restless, irritable, and unreasonable. And sometimes; even after the patient recovers, this attitude continues with lasting effect.
