WORRY AND FEAR
Now as to worry. It has been said, and not untruly, that one of the very largest causes of worry is bodily weakness. And in more than a majority of cases this weakness comes from poor physical condition. A good digestion and proper elimination seem to make the organism move smoothly, not alone with muscles, but with nerves. Hence if we get the engine right, the lungs doing their duty, the skin acting as it should, and the bowels and kidneys taking off the waste products, we generally find a robust man, little given to that most expensive habit, "worry."
Fear is the forerunner of illness.
There is nothing quite so effective in producing a bad condition of the human system as fear, and this fear is what worry develops into; later it becomes pure, downright cowardice.
Worry makes cowards. If a man has enough worry and anxiety, fear follows in its wake, and then the man becomes a mental and moral and often a physical coward.
