If we could give every individual the right amount of nourishment and exercise, not too little and not too much, we would have found the safest way to health.
As long as a person exercises, exerts himself greatly, does not eat to the point of being overly full, and keeps his bowels soft, illness will not come upon him and his strength will increase.
