1. Necessity for Food. Activity is everywhere followed 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 exactly 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
