Nobody Grows Old Merely by Living a Number of Years.

"Nobody grows old merely by living a number of years. We grow
old by deserting our ideals. Years may wrinkle the skin, but
to give up enthusiasm wrinkles the soul."

-- Samuel Ullman

Most of us grow up and become old in having something for profit and development we want.

Growing into your future with health and grace and beauty doesn't have to take all your time.

"Growing into your future with health and grace and beauty
doesn't have to take all your time. It rather requires a
dedication to caring for yourself as if you were rare and
precious, which you are, and regarding all life around you as
equally so, which it is."

-- Victoria Moran

Maintaining our health requires time and dedication. It is not necessary to devote your time to it,
