Skip this book. If I could give it negative numbers, I would. It isn't worth the ink and paper used to publish it. The first page turned me off so completely that I skimmed the rest of the book in about 10 minutes. For a book on how to improve your memory, I am struck by the method proposed by the author. That method involves remembering shocking and often obscene images as a way of providing a mental peg on which to hang the memory. My issue is, if you have to remember images of defecating or being kicked in the groin to have a mental peg (and those are mild compared with some of the images), then is what you want to remember worth making your mind filthy? My answer is no.
