1. Necessity for Food. Activity is everywhere fol- 

 lowed by waste. The engine uses up coal and water to 

 produce motion, the stream wears away its bank, the 

 growing corn-blade draws tribute from the soil. When the 

 human body acts, and it is always in action during life, some 

 of its particles are worn out and thrown off. This waste 

 must constantly be repaired, or the body suffers. In this 

 fact is seen the necessity for food. The particles, thus worn 

 out, being henceforth useless, are removed from the body. 

 Our food and drink are rapidly transformed into a new 

 supply of living, useful material, to be in turn used up 

 and replaced by a fresher supply. 



2. Waste and Repair. In this way the healthful 

 body, though always wasting, is always building up, and 

 does not greatly change in size, form, or weight. At two 

 periods of life the processes of waste and repair are not ex- 

 actly balanced. In early life the process of building up is 

 more active, and in consequence the form is plump, and 

 the stature increases. Repair now exceeds waste. On the 

 other hand, when old age comes on, the wasting process is 

 more active, the flesh and weight diminish, the skin falls 

 in wrinkles, and the senses become dull. Only during the 

 prime of life from about twenty to sixty years of age is 

 the balance exact between loss and gain.
