OUR BODIES AND HOW WE LIVE 



a daily walk of five miles along a level road. Growing 

 children, as a rule, take more exercise than this ; while 

 most men in the prime of life working indoors take nothing 

 like this amount, and many women take 

 even less. If one's daily work is active 

 and outdoor, no additional exercise is 

 really necessary. The age is an impor- 

 tant matter. A young man or young 

 woman may easily and safely take an 

 amount of exercise that might do much 

 harm to a person in advanced life. 



Exercise may be varied in many 

 ways, the more ways the better. But 

 for the most part it should be taken 

 in the open air. 



82. Time for Exercise. The best 

 time to take exercise is about two 

 hours after a meal. It is not' well to 

 do. hard work or take severe exercise 

 before breakfast. Those who go to 

 work or study before this meal should 

 first eat half a slice of bread, or a bis- 

 cuit, or even drink a glass of milk, 

 just enough to "stay the stomach," 

 and thus save the feeling of faintness 

 or " sinking." 



Just after a full meal the stomach 

 is busily doing its duty. Exercise at 

 this time is apt to retard its action 

 and result sooner or later in dyspepsia.
