This is a somewhat older book, so I wonder if any of the information is outdated. Still, it's filled with good, practical advice and exercises. I find it very useful when I'm suffering from neck tension and headaches. I've always been leery of chiropractic, so I put this book off even though I've owned it for years. But there's nothing to be hesitant about -- it's all exactly what the title says: simple and natural.
