Since i began following a vegetarian diet ten years ago , apart from the elimination of my anemia , i no longer have bronchitis attacks , and the excess pressure in the inner ear that i used to suffer from has also disappeared . after these conditions went away , my only remaining physical complaint was an occasional arthritis attack due to lack of exercise
