the race any thought. Every individual who leads a natural life and
thinks to advantage helps to bring about better public health. The
national health is the aggregate of individual health and is improved as
the individuals evolve into better health. National or racial
improvement come through evolution, not through revolution. The
improvement is due to small contributions from many sources.

The greatest power for human uplift is knowledge. Reformers often
believe that they can improve the world by legislation. Lasting reform
comes through education. If the laws are very repressive the reaction is
both great and unpleasant.

It takes about six months to learn stenography. It requires a long
apprenticeship to become a first-class blacksmith or horseshoer. To
obtain the rudiments of a physician's art it is necessary to spend four
to six years in college. To learn a language takes an apt pupil at least
a year. A lawyer must study from two to four years to become a novice. A
businessman must work many years before he is an expert in his line. Not
one of these attainments is worth as much as good health, yet an
individual of average intelligence can obtain enough knowledge about
right living during his spare time in from two to six months to assure
him of good health, if he lives as well as he knows how. Is it worth
while? It certainly is, for it is one of the essentials of life. Health
will increase one's earning capacity and productivity and more than
double both the pleasure and the duration of life.

Disease is a very expensive luxury. Health is one of the cheapest,
though one of the rarest, things on earth. There is no royal road to
health. If there is any law of health it is this: Only those will retain
it permanently who are deserving of it.
