Exercise
Bodily exercise, when compulsory, does no harm to the body; but knowledge which is acquired under compulsion obtains no hold on the mind.
Plato (427 BCE-347 BCE)
Eat right, exercise regularly, die anyway.

To exercise I keep the wolf from the door, let the cat out of the bag, take the bull by the horns, count my chickens before they are hatched, and see that the horse isn't put behind the cart or stolen before I lock the barn door.
Frank Sullivan (1892-1976)
