This is fascinating reading, although a bit complicated.  I read about this while I was in college back in 1972 and it struck me as being so profound, and yet it was totally ignored by the "science" people.  I never could figure out why until recently, with the money-hungry medical and drug companies taking over our health.  I don't even call it health CARE anymore, because it's not.

Great reading though.
