You wander hither and yon, to rid yourself of the burden that rests upon you, though it becomes more troublesome by reason of your very restlessness, just as in a ship the cargo when stationary makes no trouble, but when it shifts to this side or that, it causes the vessel to heel more quickly in the direction where it has settled. Anything you do tells against you, and you hurt yourself by your very unrest; for you are shaking up a sick man.
