One of the books I have in my library was written in 1919, almost a hundred years ago. A lot of wisdom about treating disease, one being combative and the other prevention.
I have a great deal of interest in Universal Law and natural methods of healing.
Back in the forties living in Tennessee, one day I pulled out this very powerful microscope, inherited from my father-in-law, who was a graduate electrical engineer from a college in Illinois. The microscope was one he used in college. Accompanying the microscope were dozens of slides. One slide had the tooth of a gnat on it. It was news to me gnats had teeth, but there it was on a slide.
