Dr. McClatchie, a pathologist of 40 years' experience in Canada, the Orient, Kenya and Tanzania, writes a fair amount of common sense with which the more sophisticated reader will be familiar. Others may have picked up the tab in one way or another. Essentially he is working toward rehabilitative or preventive medicine and against the excesses of irrelevant research (utilize what we have; call a moratorium), mechanization, overdosing (this often leads to that iatrogenic or doctor-induced disease), the ""complete"" examination which is anything but, etc. etc. These are all endemic problems -- so too are hookworm and roundworm, rampant malaria, tuberculosis, VD and arteriosclerosis. En route he touches on the inflationary economics of illness, the maldistribution of doctors, the dangers of overspecialization, while plumping for better living habits and conditions. Admittedly casually written at a vox pop level representing a whole world view of backward, underprivileged countries and the ecological balance of nature Compoz cannot restore.
