r the desk chair should fit the human back. It. should
favor and not hamper one in assuming a normal and straight position
of the spine.

When you get up in the morning, exercise yourself a little in
straightening the spine, chin in, downward and backward. When you walk
to business or when you go about your duties, keep the same thought in

in the next chapter, referring to the thyroid gland, at very frequent
intervals during the day.

Remember that in fighting for a straight spine you are fighting for
youth and health and life and energy and courage and enthusiasm. You
are fighting for everything that is best in life, and you should strive
and struggle with all the energy you possess to win the rewards
associated therewith.

inclinations with all the power you possess. Struggle against such
discouragements with all your might and main, not only through your
mental attitude but through your determination to maintain an erect
spine. Hold your head up and look the world in the face.

Don't shirk your duty. Don't deviate from the path along which your best
impulses and highest ideals would lead you. Life is worth while. It is
filled with glorious opportunities. Reach out and grasp them as they
come up. Hold your head up and be a man or a woman to the fullest extent
of your abilities.

CHAPTER IV: Stimulating the Source of Stamina and Vitality

This is an age of short cuts. Any devious routes to the accomplishment
of an object should be avoided. If you want vitality, and the
vivacity, energy and enthusiasm with which it is associated, you
naturally search for a method which will bring certain and quick
improvements. The reasonableness and general prevalence of this demand
was in my mind when I began experimentation with a view to
discovering a method for stimulating what I term the source of vital
power.

Scientific men while delving into the marvelous secrets of physiology,
have learned that the thyroid gland in some peculiar manner possesses
an extraordinary influence upon vital stamina and virility. This
mysterious gland is located in front of the
