There is one point of special importance in connection with our exercise and that is to cultivate the play spirit. You will never fully enjoy your sports and you will never obtain all possible benefit from them until you lose your dignity and learn how to play. Try to be glad that you are alive and able to play these games. One great drawback to American sports is the tendency to take them too seriously. There is too much of strained effort involved in the desire to win the game at any price. Keep yourself in a state of mind where you "see the fun." Though "playing to win" may be commended, the real purpose of any game is the fun and benefit that is secured therefrom whether you win or lose. There have been cases when members of a boat crew or a football team have actually cried over a lost game. Imagine the nerve strain involved in taking athletics so seriously! It is splendid to win, but it should also be pleasurable to lose to a worthy antagonist. Do not take your games too seriously, but make them a laughing matter. Only by assuming this attitude can you get the greatest possible benefits that can be derived from games. The nature of your exercise does not matter so long as there is that increased activity of the heart, lungs and other organs which tends to improve the circulation throughout the entire body. The exercise must insure deep breathing, and if a certain amount of perspiration is induced it will be advantageous. First of all get out-of-doors; find some exercise that appeals, some alluring attraction which will take you away from the confinement of your home. Live as much as you can in the open. If possible, try sleeping out-of-doors. Men and women of today may be aptly compared to sensitive plants. We are the devitalized product of the universal custom of coddling, and the less we live within four walls, and the more we breathe the free outdoor air, the stronger, healthier and more capable we become. There is one outdoor exercise that we can all take without expense, and it is by far the best when everything is considered. At least this statement is true so far as the building of vitality and endurance is concerned. I refer to walking. This is an exercise that can be made decidedly vigorous if desired. And no matter what health-building regimen you may follow, a certain amount of walking is essential to maintaining the highest degree of physical vigor.
