Life and Health 



this period of life is of great importance in the physical 

 development of the body. If at this age a boy or girl is 

 subjected to undue physical strain, the development may 

 suffer, the growth be retarded, and the foundation laid for 

 future ill health. 



107. Time for Exercise. It is not prudent to do hard 

 work or take severe exercise just before or just after a full 



meal. While the 

 stomach is busily 

 digesting food vigor- 

 ous exercise may 

 prove injurious, and 

 is apt to result sooner 

 or later in dyspepsia. 

 Hence the best time 

 to take exercise is 

 one or two hours 

 after a meal. 



On the other 

 hand, severe exer- 

 cise should not be 

 taken on an empty 

 stomach. Those 

 who do much work 

 or study before 

 breakfast should first take a light lunch, just enough to 

 prevent any faint feeling. With this precaution, there 

 is no better time for moderate exercise than the early 

 morning. 



108. Walking, Running, and Jumping. Walking is gen- 

 erally regarded as the simplest and most convenient mode 

 of taking exercise. When taken with a special object in 

 view, it is the best and most pleasant of all physical
