Health of Workers—Those who put their whole souls into the medical missionary work, who labor untiringly, in peril, in privation, in watchings oft, in weariness, and painfulness, are in danger of forgetting that they must be faithful guardians of their own mental and physical powers. They are not to allow themselves to be overtaxed. But they are filled with zeal and earnestness, and they sometimes move unadvisedly, putting themselves under too heavy a strain. Unless such workers make a change, the result will be that sickness will come upon them, and they will break down.
