GOOD HEALTH 



that point. Here is another point quite as important. 

 When you come into the school building to-morrow 

 morning, if you count your pulse at the foot of the stairs 

 (provided that you have not been running just before 

 that), you will find it beating quietly. But walk rapidly 



to the top of the building 

 and count the rate of your 

 heart beats again for a 

 whole minute, and you will 

 notice a great change; your 

 pulse will now be pounding 

 violently. 



The experiment shows 

 that exercise increases not 

 merely the breathing but 

 also the circulation of the 

 blood in the body. 



The easiest way to feel 



the pulse is to put the hand 

 FEELING THE PULSE Qn the gide of the wrist 



toward the thumb. There you may count from seventy 

 to one hundred pulse beats a minute. Sometimes hard 

 exercise drives the pulse up to one hundred and fifty, 

 but this is too fast. At other times, when one is lying 

 very quiet, having been still a long time, it will beat 

 much slower than seventy; and it is then that the 

 heart does its resting.
