But if the sickness with which the deceased was attacked and of which he died, was a chronic disease, the progress of which was slow and which only occasioned death after a long while, then the privilege shall only commence from the time when the malady became so serious as to prevent the deceased from attending to his business and confined him to his bed or chamber.
