EXERCISE 167 



Upon discovering that unclean food has been taken into 

 our mouths, how quickly we eject it ! We know that 

 the atmosphere of crowded rooms must be more or less

 retained, and eagerly refresh the lungs with extra 

 quantities of pure air. 



Breathing exercises are not usually necessary for 

 adults engaged in hard physical labor, especially if 

 their employment be out-of-doors. However, those 

 whose work is largely mental, or persons who are weak 

 or not well developed, can improve greatly by prac-

 store up capital in the form of healthy, capacious 

 breathing organs that will furnish them a most 

 bountiful supply of life's very best form of wealth, 

 good health. But some children may say, "I am 

 growing stronger and broader chested as the years 

 go by, and my general health is excellent without 

 giving these matters any particular attention." Some 

 are fortunate enough to have such good bodies, and 

 while deep-breathing exercises might make them even 

 stronger and healthier, there may be no great need of 

 care and practice for them.
