"Back pain can be comfortably cured just by "arching your back and lying on your stomach"" Yoshiyasu Miura Price: ¥952 I bought this when my husband was suffering from severe back pain. It's a good book that explains the causes of back pain and tips for prevention in an easy-to-understand way, with plenty of photos. There are no stains or folds, and it's almost like new, but please understand that it is a used item. #YoshiyasuMiura #book #lifestyle/housework
