It is a mark of a mean capacity to spend much time on the things which concern the body

"It is a mark of a mean capacity to spend much time on the things which concern the body, such as much exercise, much eating, much drinking, much easing of the body, much copulation. But these things should be done as subordinate things: and let all your care be directed to the mind."

by Epictetus, 2nd century c. 135 AD.
