THE MICROBES THAT MAKE US SICK 77 
everyone who lives in a city, where there are 
so many germs of all kinds floating around, has 
inhaled or swallowed some tuberculosis germs, 
but it is only when one’s body is weakened that 
they multiply enough to cause illness. Among 
the conditions that weaken the body so that 
the tuberculosis germs can no longer be con¬ 
trolled are: living in a damp place, leading an 
indoor life without healthful exercise, eating 
too little food, or the wrong kind of food, and 
working in a very hot or damp atmosphere. 
The disease, if discovered early enough, can 
often be cured by a change to a more healthful 
way of living, or in more serious cases, by 
moving to a dry, warm climate, like that of 
Arizona or California. Complete rest in order 
to leave all the energies of the body free to fight 
the germs, and plenty of fresh air and sunlight 
are the best remedies for fighting this dread 
disease. 
Lockjaw is a disease that is marked by 
painful cramps in various muscles of the body, 
especially those of the jaw and neck. Hence 
When do they 
cause trouble?
