A study of climate as an outside force and master of man's destiny and how it works. From laboratory study to research throughout the world, with evidence and probabilities weighed, this really makes extremely interesting reading for minds open to unusual theories. The contrasts of tropical, temperate and cold climates, and the effects on the human system, the linking of nutrition, weather, disease, fertility, health with various climates -- this provides curious and fascinating information about hygiene, some rebuttals of common beliefs, and not a little amusing personal experience. Written by a doctor of experimental medicine. A book that might well attract absorbed attention and curious comment. But a book that needs personal selling.
