The issue of people whose lives are out of balance is not a new one and philosphers through the ages have urged moderation:
Be moderate in order to taste the joys of life in abundance. ~Epicurus
They are sick that surfeit with too much, as they that starve with nothing. ~William Shakespeare
To go beyond is as wrong as to fall short. ~Confucius, Analects
Everything in moderation, including moderation. ~Author Unknown
No matter what happens... somebody will find a way to take it too seriously. ~Dave Barry, "Things That It Took Me 50 Years to Learn"
