Fashion in our time is seen mainly from a fashion point of view. But the skin is an organ which is strongly neglected in this function. Prof. Jaeger's concern was not to treat a person only when he has become ill, but to consider beforehand what kind of behavior in daily life can lead to illness. Self-poisoning and disposition to infectious diseases were therefore of great concern to him, and he had developed a method to measure the influence of clothing fibers on nerve conduction velocity. Animal fibers were far superior to plant fibers. What this is all about and why clothing should definitely be made of animal fibers is what you will read in this interesting book. You will be surprised how much you can do for your health with simple means. The book is therefore more topical and important than ever!
