The Doctor and His Patient
A doctor had been for some time attending upon a sick man who, however, died under his hands. At the funeral the doctor went about among the relations, saying; "Our poor friend, if he had only refrained from wine, attended to his insides, and used proper means, would not have been lying there."
One of the mourners answered him, "My good sir, it is of no use your saying this now; you ought to have prescribed these things when your patient was alive to take them."
The best advice may come too late.
