=Exercise in the open air.=--Exercise quickens the heart-rate, and thus the blood requires a greatly increased amount of oxygen. One should therefore never exercise in an unventilated room, and for this reason exercise in the open air is vastly more beneficial than when taken indoors. In fact, one should get outdoors often and where circumstances admit the outdoor life (a phrase on everyone’s tongue these days) should be lived as much as possible. One should not, of course, fail to adopt a special system of exercises, for this insures that every muscle will be regularly used, and it is quite likely that one’s activities, whether outdoors or indoors will but partly use the muscular system. Of outdoor exercise, walking is ideal, and can be taken at all seasons. And, of course, all outdoor games and sports are valuable. Exercise in play is the thing, for it so completely diverts the mind as well as recreates the body. Of all exercises, I personally regard, and authorities support my views, swimming as first in rank, the peer of them all. Every muscle is exercised by it, it is taken in the open air, and then there is the tonic of the water. =Diet.=--There are other measures of which it is necessary to speak and they are too important to miss mention. She who seeks to improve her appearance or preserve it unblemished cannot afford to neglect her diet--for remember that it is from food that flesh and blood are formed. In greater or lesser degree, bad food and that improperly eaten can retard improvement from other measures followed. It is impossible to do more than briefly pass on this subject in its relation to this discussion on how beauty can be attained. It is of chief interest to point out that even where no other factors are at work, disfiguring eruptions on the face are not infrequently caused by errors in this respect. To be sure there are no special “beauty diets.” The only thing that is necessary is to avoid such foods as cause a maximum of work on the part of the vital organs, and give only a minimum of nutriment in return. Rich, heavy pastry, pickled foods, white flour products, are all in the above-mentioned class, while cereals, eggs, milk, cheese, nuts, fruits and vegetables, rightly prepared, properly masticated, can be depended upon to make good, rich, red blood, firm flesh and muscle, and altogether help greatly in enhancing personal charm and appearance.
