GOOD HEALTH 



but we never suspect that a man with some kind of 

 disease microbes on his hands may have just let go that 

 same rail and left his microbes there. 



We push a shop door open with both hands ; yet who 

 knows what sort of woman with what sort of disease may 



have pushed it open 

 two minutes before we 

 came? Thus in a hun- 

 dred ways we may 

 gather up the worst of 

 the city microbes. We 

 may then reach home 

 barely in time for din- 

 ner and, if we forget 

 to wash our hands, we 

 give all sorts of mi- 

 crobes from all sorts of 

 people the chance to 

 go into our mouths 

 with our food. 



Wearing gloves is quite a help, although even those 

 who wear them are sometimes very careless. I have 

 seen a gentle-looking, well-dressed woman with gloves 

 on slip a penny between her lips for a moment. It was 

 a dangerous thing to do, because who could tell what 

 hand had held the penny before she held it, or what 

 kind of microbes might be on it ?
