SAFEGUARDS OF THE BODY 151 



on the part of those who make the preparations and 

 skill and judgment in those who advise and administer 

 them. With these things "the man in the street" has 

 nothing to do. But it is for him to see to it that no 

 fad or ism, no false guides, nor ignorance, nor indif- 

 ference shall hold him from seeking and following 

 wise medical counsel in the face of any of the mala- 

 dies from which artificial immunity may be secured 

 today. Here ignorance is folly, indifference, crime. 



On the other hand, it should not be forgotten that 

 underlying all these protective measures is the living 

 body machine, which each controls for himself. If, 

 through the various phases of unwholesome living so 

 largely in evidence today, the machine is lacking in 

 vigor, then by so much are the chances of recovery 

 lessened when the shadow of disease falls across our 

 path. 



Not too much work nor too much play; not too 

 much food and drink, but enough ; good air and in- 

 telligent cleanliness in houses, assembly places and 

 public conveyances if these conditions be fulfilled in 

 such way and measure as the hygiene and sanitation 

 of the day demand, we shall go far to establish our 

 birthright to threescore years and ten. And our im- 

 munity to infectious disease, whether we brought it 

 into the world with us, or achieve it under the minis- 

 trations of the physicians, will most closely confirm 

 the promise of science.
