Query: A healthy side of pseudo science with your massage

This book is fine if you confine your reading to the chapters on Swedish massage. Most of the other sections are loaded with silliness, including admonitions not to practice certain massage techniques during eclipses or earthquakes. These other techniques are discussed in such a vague, airy manner that I honestly don't know how someone would evaluate whether they had learned them properly or not.
