Is the natural sequence of correct attitude in standing and may be readily acquired by attention. Stand against the wall, with the heels, limbs, hips, shoulders and head all touching and draw the chin inward to the chest. When in this position you will find it uncomfortable, mainly because it is incorrect. Gently free yourself from the wall by swaying the body forward, from the ankles only, keeping the heels touching. You will then be in the correct position, and should walk off, carefully maintaining it. This exercise, if constantly practiced, will give you an easy and graceful carriage that will be the envy of your less fortunate acquaintances. In the foregoing list of exercises we have carefully omitted all those requiring apparatus of any kind, selecting only such as can be practiced in the privacy of your own room, without assistance from an instructor or paraphernalia of any kind. Dumb bells, Indian clubs, etc., are valuable after a certain degree of muscular improvement has been attained, but when that point is reached we should advise the individual to join a gymnasium and practice further development under a competent instructor. All the exercises given have been proved of great value in building up the system, and are designed as aids to the preservation of health and the upbuilding of weakly people--not to develop trained athletes. These exercises bring into play a number of muscles that are not called into general use, and thus promote harmonious development of the whole body. PART VII. THE DIET QUESTION. As we have already stated, the human system is in a state of constant change. Disintegration of tissue is taking place during every moment of existence, and the preservation of health depends upon the prompt elimination of the waste material. But the destruction of tissue, due to the daily friction of life, must be made good, and this replacement of substance is effected by the food we eat. It becomes a matter of vital importance, therefore, to every individual to consider the question of eating from the rational standpoint. Owing to the increased prosperity of recent years and the luxurious mode of living rendered possible by it, people have been betrayed into many reprehensible gastronomic practices. In the olden days, when man toiled hard for existence, food was produced within his own immediate radius and luxuries were unknown; but now, with rapid ocean transportation, the ends of the earth are ransacked and laid under tribute to furnish delicacies to tempt the palate. The ease with which food may now be procured and the almost illimitable variety offered to man for his selection has tempted him into indulgences that have been productive of much evil. Although over indulgence in eating is a very ancient offense, yet, as before stated, the multiplicity of foods has given an impetus to this injurious habit, in combination with the cunningly devised methods of preparation which the modern cook has evolved.
