It shows poor judgment to spend too much time on bodily things. Don't overdo exercise, eating, drinking, or other basic physical needs. Handle these things quickly and put your main energy into developing your mind.
It is a mark of want of intellect to spend much time in things relating to the body, as to be immoderate in exercises, in eating and drinking, and in the discharge of other animal functions. These things should be done incidentally and our main strength be applied to our reason.
