Query: What is this total quack stuff?

This was a great book from a patients perspective of the lower back mechanics in an acute pain phase. Despite the ? review above from one Brownyn Scot, who reviews the book with the header 'a total quack' I would have to remark that the uneducated, myself included, have too much free space on the Internet to say supposedly learned things of which they know not, except definately crock pots :) The book helped. Enough said.
