We can find, perhaps, no better instance of the necessity for the application of the principles of conscious control to these fundamental and essential propositions of standing, walking, and running, than in the photographs taken of Dorando as he appeared when he was making his last terrible efforts to reach the tape at the conclusion of the Marathon race in London in 1908. One sees that he was desperately wearied, and that whatever conscious control of his muscular mechanisms he may ever have obtained, he was at this moment completely under the domination of subconscious (or subjective) control, that he was out of “communication with his reason.” His body, as we see him in these photographs, is thrown back from the hips, his arms are outstretched behind him, and his legs are bent forward at the knee. As a consequence, he is compelled to use almost all his physical force in order to save himself from falling backwards. He is struggling against a tremendous gravitational pull which is dragging him away from his goal. If Dorando, magnificent athlete as he undoubtedly is, had been trained in the principles of conscious control, such an attitude would have been impossible for him, tired and exhausted even as he was. For if he had not been subconsciously controlled, he would have employed his common-sense at this moment and would have acted according to the guidance of its mandate. It is at such critical moments that we have urgent need for the control of reason, for it is then that we suffer most from the loss of the animal equivalent—instinct. Dorando’s muscles may have been taxed to their utmost capacity, but if he had been consciously controlled he would have leaned forward, not back, and while he had the strength necessary (but a very small part of the strength he was actually expending) to prevent himself from falling on his face, that gravitational force would have dragged him on instead of dragging him back from the object of his achievement, as was actually the case. He would, in short, have been able to make the _best_ instead of the _worst_ use of his powers. Faults such as we see exaggerated in this instance are to be found in the carriage of many people to-day, and the fact is one of great importance to medical men. Patients are constantly advised to take walking exercise, although in many cases that exercise undoubtedly does more harm than good. In my opinion it is very essential that all doctors should devote more attention to this subject than they are devoting at the present time, in order that they may be in a position to advise which of their patients will be benefited by taking walking exercise, and which of them by so doing will aggravate the troubles from which they are suffering. For it should be evident, I think, that the good effects of fresh air and gentle exercise will be practically nullified, if the patient can only obtain them by exaggerating and perpetuating the defects which have led him to the prescription.
