Even the Greek philosophers murmured that physical powers in matters
of sex did not always parallel brain capacity. Strange that the sex
instinct should be so deeply rooted and so prominent in life that
two thousand years of experience has failed to convince men of the
truthfulness of that statement.
Modern science has shown that the early detection of signs of disease
by physical examination, and the establishment of a proper regime of
life, including adequate rest, diet, exercise, simple personal hygiene,
and freedom from worry will greatly extend the life of the average
man. He may quite reasonably hope to live to seventy years and if he
is at all careful considerably beyond that age. It behooves him then
to grow old gracefully, remembering that much of the greatest work of
this world done in art, letters, invention, finance and statesmanship
has been done by men well beyond sixty years of age. Their minds were
perhaps little given to the purely pleasurable functions of the bodies
which constituted the abodes of their restless spirits.
