Whether the disease called “Spanish influenza” is simply our old enemy the grip [another word for the typical flu], as physicians seemed to think in the beginning, or whether it differs in important respects, its menace will be increased by excitement and hysteria. Not that it is a thing caused by a nervous imagination, but because those who give way to the fever of nervousness are helping to break down their own physical defenses and to put themselves in a condition favorable for attack. The best protection against this or any other disease is to keep yourself in the highest possible physical state of defense, and then, even if you are attacked, your resisting power will be all the greater and your chances of speedy recovery all the brighter. Excesses of any kind, unsanitary habits, worry, undue fatigue — all these are allies of every prowling ill to which flesh is heir. Therefore, the first thing to do now is to put and keep your body in a first-class state of defense and to cut out all the influences that may weaken it.
