Such mental exercise as playing cards, chess, and checkers, excites and wearies the brain and hinders recovery: while light and pleasant physical labour will occupy the time, improve the circulation, relieve and restore the brain, and prove a decided benefit to the health. But take from the invalid all such employment, and he becomes restless, and, with a diseased imagination, views his case as much worse than it really is, which tends to imbecility.

that the sick should be taught that it is wrong to suspend all physical labour in order to regain health. In thus doing the will becomes dormant, the blood moves sluggishly through the system, and constantly grows more impure. Where the patient is in danger of imagining his case worse than it really is, indolence will be sure to produce the most unhappy results. Well-regulated labour gives the invalid the idea that he is not totally useless in the world, that he is, at least, of some benefit. This will afford him satisfaction, give him courage, and impart to him vigour, which vain mental amusements can never do. -- "Testimonies," Vol. I, page 555.
