Physical exercise and labour combined have a happy influence upon the mind, strengthen
the muscles, improve the circulation, and give the invalid the satisfaction of knowing his
own power of endurance; whereas, if he is restricted from healthful exercise and physical
labour, his attention is turned to himself. He is in constant danger of thinking himself
worse than he really is, and of having established within him a diseased imagination,
which causes him continually to fear that he is overtaxing his powers of endurance. As a
general thing, if he would engage in some well-directed labour, using his strength and not
abusing it, he would find that physical exercise would prove a more powerful and effective
agent in his recovery than even the water treatment he is receiving.--
