In addition to the above, you can devise fresh ones as you go along. A good plan is to take each joint in turn, and exercise it. Thus, start with the fingers, clasping and unclasping the hand. Then clench the fist and move the wrist up and down. Do the same with the elbow and shoulder, and with the different joints of the lower extremities. Then bend the body backwards and forwards, and the head in the same way. After all that, there will be few muscles in the whole body that have not received their due attention. The value and the enjoyment of these exercises can be increased very much by getting other people to join you in them. It is easier to persevere with anything if we have the society of others to encourage us. There is a spirit of emulation introduced which is always conducive to success. [Sidenote: Imitation of games.] If you are so fortunate as to have an empty room or shed, there is nothing better than to practise an imitation of some outdoor game, such as playing tennis against a wall. There is a zest about such exercises which makes them more profitable than those which are carried on merely from a sense of duty. One of the finest forms of exercise is that of skipping, both for men and women. The former need not look upon it as a feminine pursuit, seeing that some of the best-known athletes and boxers employ it as a means of training. It is simply astonishing what a difference exercise, either outdoor or indoor, makes to those who carry it out systematically. After a few weeks pale, languid people begin to acquire a healthy colour and a sense of vigour they have never known for years; dyspeptic ones may forget that they ever had a stomach; whilst headaches that have been a curse for years are sometimes seen to disappear like magic. Life becomes brighter, for health and happiness go together, and the whole outlook becomes more cheering. [Sidenote: Massage.] All these are active forms of exercise, but there is another sort which needs mention, viz. the passive, or massage, as it is termed. Some people either through general weakness or some infirmity are unable to take exercise for themselves, and in such cases massage is of great benefit, acting in the same way, but without any exertion on the part of the patient. The full consideration of this subject would need a volume of its own, and this is hardly the place to discuss it in greater detail. One important fact, however, requires mention. It is imperative that a prolonged rest of an hour or two at least should be allowed after each rubbing. One hour of massage is equivalent to several hours of active movement. CHAPTER XIII.
