passing car, with keenest interest until it was out of sight, clearly
revealing the jealousy, worry, and unrest he felt.

In another chapter I have dealt more fully with the subject of
the worries of jealousy. They are demons of unrest and distress,
destroying the very vitals with their incessant gnawing.

Too great emphasis cannot be placed upon the physical ills that come
from worry. 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_
