The body unconsciously reflects our mental states.

A fretful and worrying mother should never be allowed to suckle her child, for she directly injures it by the poison secreted in her milk by the disturbances caused in her body by the worry of her mind.
Among the many wonderfully good things said in his lifetime Henry Ward Beecher never said a wiser and truer thing than that "it is not the revolution which destroys the machinery, but the friction." Worry is the friction that shatters the machine.

Work, to the healthy body and serene mind, is a joy, a blessing, a health-giving exercise, but to the worried is a burden, a curse and a destroyer.
Go where you will, when you will, how you will, and you will find most people worrying to a greater or lesser extent.

Indeed so full has our Western world become of worry that a harsh and complaining note is far more prevalent than we are willing to believe, which is expressed in a rude motto to be found hung on many an office, bedroom, library, study, and laboratory wall which reads: _Life is one Damn Thing after Another_ [Note: this is outlined in a block.] Those gifted with a sense of humor laugh at the motto; the very serious frown at it and reprobate its apparent profanity, those who see no humor in anything regard it with gloom, the careless with assumed indifference, but in the minds of all, more or less latent or subconscious, there is a recognition that there is "an awful lot of truth in it." Hence it will be seen that worry is by no means confined to the poor.
The well-to-do, the prosperous, and the rich, indeed, have far more to worry about than the poor, and for one victim who suffers keenly from worry among the poor, ten can be found among the rich who are its abject victims.
It is worry that paints the lines of care on foreheads and cheeks that should be smooth and beautiful; worry bows the shoulders, brings out scowls and frowns where smiles and sweet greetings should exist.

Worry is the twister, the dwarfer, the poisoner, the murderer of joy, of peace, of work, of happiness; the strangler, the burglar of life; the phantom, the vampire, the ghost that scares, terrifies, fills with dread.
