“To drink when thirsty is right and natural; it shows that the blood is concentrated and is in want of fluid. But to drink merely for the pleasure of drinking, or to carry out some insane theory like that of ‘washing out’ the system is positively dangerous. The human body is not a dirty barrel needing swilling out with a hose-pipe. It is a most delicate piece of mechanism, so delicate that the abuse of any of its parts tends to throw the entire system out of order.”
