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

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

 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
