All the physical organs are the servants of the mind, and the nerves are the messengers that transmit its orders to every part of the body, guiding the motions of the living machinery. Exercise is an important aid to physical development. It quickens the circulation of the blood, and gives tone to the system. If the muscles are allowed to remain unused, it will soon be apparent that the blood does not sufficiently nourish them. Instead of increasing in size and strength, they will lose their firmness and elasticity, and become soft and weak. Inactivity is not the law the Lord has established in the human body. The harmonious action of all the parts,—brain, bone, and muscle,—is necessary to the full and healthful development of the entire human organism. (FE 426.1) MC VC

The work of physical training, begun in the home, should be carried on in the schools. It is the design of the Creator that man shall know himself; but too often in the pursuit of knowledge this design is lost sight of. Students devote years to different educational lines; they become engrossed in the study of the sciences and of things in the natural world; they are intelligent on most subjects, but they do not become acquainted with themselves. They look upon the delicate human organism as something that will take care of itself; and that which is in the highest degree essential—a knowledge of their own bodies—is neglected. (FE 426.2) MC VC

Every student should understand how to take such care of himself as to preserve the best possible condition of health, resisting feebleness and disease; and if from any cause disease does come, or accidents occur, he should know how to meet ordinary emergencies without calling upon a physician, and taking his poisonous drugs. (FE 426.3) MC VC
