How to Eat A cure for Nerves?

Any discourse is valuable which incites a man having a marked tendency
to depressing, morbid ideas, to rid himself of them. Dr. Hinkle helps
the sufferer to gain that confidence and cheer which result from
knowledge of certain immunity from dreaded ills and positive assurance
of recovery by mere regulation of food or employment along the lines of
simple, everyday living.

But that alone is not sufficient. It is made quite clear that no one
thing by itself will insure a cure of "nerves." The cure must come
through common sense exerted along several related avenues of endeavor.
No matter how steadfastly one may adhere to directions as to abstaining
from harmful food and injurious methods of partaking of those foods
which are beneficial, if he spends the larger portion of his time idly
rocking in a convenient arm chair, exerting neither body nor mind nor
will, that which might be gained by proper nutrition is largely
nullified by lack of physical exercise and mental activity.
