Health is a great wealth. But when a man is healthy, he does not value this blessing. He realizes its value when even a mild malady strikes him. If a part of body suffers from pain, the whole body is affected by it. Being healthy, a man enjoys eating, strolling and working. Being sick, he does not enjoy anything. The life of those who remain often ill becomes a terrible burden not only for them but also for their relations. Ailment causes not only pain, but also medical expenses. An ailing person becomes a living corpse.
