You must keep a strict eye on your health; let everything else be subordinated to that.

To keep the body in good health is a duty... otherwise we shall not be able to keep our mind strong and clear.

It is health that is real wealth and not pieces of gold and silver.

The only way to keep your health is to eat what you don't want, drink what you don't like, and do what you'd rather not.

If you would seek health, look first to the spine.

Give a man health and a course to steer, and he'll never stop to trouble about whether he's happy or not.
