Health for the body awakens mental capacities where they exist. Failure
in mental work can often be traced to failure in physical health; and
the restoration of bodily health is often essential to success in the
tasks of the mind. This is especially true of the artistic professions,
where the kind of product is dependent so largely upon the state of the
emotions, upon exhilaration and enthusiasm. A noted sculptor who, a
number of years ago, was 'down and out' in the artistic world, after a
period of years 'came back' with a masterpiece, having adopted a more
hygienic life.
