Thousands are sick and dying around us who might get well and live if they would; but their imagination holds them. They fear that they will be made worse if they labor or exercise, when this is just the change they need to make them well. Without this they never can improve. They should exercise the power of the will, rise above their aches and debility, engage in useful employment, and forget that they have aching backs, sides, lungs, and heads. Neglecting to exercise the entire body, or a portion of it, will bring on morbid conditions. Inaction of any of the organs of the body will be followed by a decrease in size and strength of the muscles and will cause the blood to flow sluggishly through the blood vessels.—Testimonies for the Church 3:76. MM 105.2
