I live out in the country close to the lake so am close to clean air and water. Whenever I fly to Toronto to seem my mother I would come back and be wiped out for almost a week. The last time I mentioned to a friend that I was going to visit my Mom again she took a pendent from around her neck and gave it to me saying “you need this more than me if you are going to the big city.” I wore the pendant and what a difference….. I came home feeling great and now realize that it was the EMF that were tiring me out whenever I went to the big city. I though the city was just polluted with smog etc but it's really the invisible pollution that gets to you. If you live in the city you should get out or wear a Iyashi emf protection pendant.
