A Science of Genius

A book I want, one that scientifically identifies the physical and chemical conditions of genius, or of productivity generally. How to sleep (if you delay it, how to avoid illness), fresh air, humidity, diet (fast? protein? vitamins?), sun exposure, exercise (aerobic or anaerobic). Not just tips on planning and prioritizing or avoiding procrastination and distraction. Varying with the kind of work: the philosopher might need isolation, the artist, a busy city.
