Some years ago I wrote in the _Pall Mall Gazette_: “I will merely point out that in our schools and in the Army human beings are actually being developed into deformities by breathing and physical exercises. I have before me a book on the breathing exercises which are used in the Army, and any person reasonably versed in physiology and psychology, and knowing they are inseparable in practice, will at once understand why so much harm results from them. Take either the officers or the men. In a greater or less degree the unduly protruded upper chests (development of emphysema), unduly hollowed backs (lordosis), stiff necks, rigid thorax, and other physical eccentricities have been cultivated. It is for these reasons that heart troubles, varicose veins, emphysema, and mouth breathing (in exercise) are so much in evidence in the Army. As this is a matter of _national importance, I am prepared to give the time necessary to prove to the authorities (medical or official) connected with the Army, the schools, or the sanatoria, that the ‘deep breathing’ and physical exercises in vogue are doing far more harm than good_, and are laying the foundations of much graver trouble in the future. The truth is that all exercises involving ‘deep breathing’ cause an exaggeration of the defective muscular co-ordination already present, so that even if one bad habit is eradicated many others—often more harmful—are cultivated.” And again in my pamphlet “Why We Breathe Incorrectly” (Nov., 1909) I wrote:
