Query: Unfortunate and sad

I had the misfortune of acquiring this book and found it filled with unproven, at times absurd theories supposedly linking ailments with some obscure physics theories. Sad to say, but ''quantum'' seems to be the buzz word these days, and is marketable in its own sense. Add ''healing'' to the title and you have a seller, no matter the content. It was a stroke of marketing genius, but morally speaking, is a sad addition to humanity's written legacy.I won't get rid of it by selling it to a used book store. Some other unwitting buyer might stumble upon it (cheap) and buy it, thereby losing his time and, worse, possibly get false hope.I have a degree in physics by the way, and though I do not claim to be an authority, I know gibberish when I read it.Fair warning to anyone considering purchase of this book.
