nse I have proved by my own experiences and by the experiences of
everyone to whom I have made this suggestion of walking alone.

The moral is this--walk every morning and walk ALONE.

ELIMINATION

The Body's Safety-First in Keeping Health

The body is made up of billions of little cells. These individual cells
are in a state of perpetual activity. They exhaust, wear away, break
down with work and rebuild on food and rest. Every process of life--the
beat of the heart, the throb of the brain in thought, the digestion of
food, the excretion of waste--all are due to the activity of groups of
highly specialized individual cells.

Every cell uses up its own material and throws off poisonous by-products
during activity. These by-products, or wastes, are very poisonous to the
individual cell as well as to the entire organism. To get rid of this
waste is one of the first duties of the system.

It is with the body, made up of its countless millions of individual
cells, just as with a city and its myriad people: the sewage of the
community must be collected and disposed of. The city forms its poisons
which we call sewage and the body its poisons, which we call excreta (or
carbonic acid, urea, uric acid, faeces, etc.) It is no more important
for a city to gather up and get rid of its poisonous sewage than for the
animal organism to collect and excrete its cell-waste. Hence, the
importance of maintaining normal and constant elimination throughout the
body.

Elimination is kept up by the alimentary tract, the kidneys, the skin,
and the lungs.

These four are the great pipe-line sewerage systems so to speak, by
which the body throws off its gaseous, liquid and solid poisons.

The lungs momentarily strain carbonic acid out of the blood and throw it
out in the expired air. They likewise exhale other noxious matters from
the system.

The alimentary tract throws off faeces, made up of the waste tissue from
the whole system, especially the digestive organs, as well as
indigestible and non-nutritious portions of the food.

The kidneys strain out urea, uric acid, and certain other poisons from
the blood and eject them through the urinary tract.

Finally the skin likewise is an excretory organ and exhales a very
definite amount of gaseous and fluid waste in the course of each
twenty-four hours.

The skin throws off from a pint to two quarts of liquid each day in the
form of vapor.

Thus, to carry on normal eliminati
