Query: this author is venemous to humanity in general

This book is realy a sad contribution to health literature. As a doctor of chiropractic I know how many people we can help keep away from the surgical knife. With proper chiropractic, x-rays are analysed to determing which bone has shifted. The shifted bone is put back in its place in the same direction that it shifted from and the problem is reduced, pressure is take of the nervous system, and biomechanics restored.
