I wasn't even expecting this to be a self-help book, but it not only entertained me, but is startlingly good at improving what was a poor memory. I had really struggled with memory books by the like of Tony Buzan, but Derren Brown's wit, imagination, clear explanation of the Loci System as well as superior version of the Major System had me remembering football results and phone numbers with ease.
Although he uses plenty of tongue-in-cheek use of superlatives to describe himself and his achievements, this book is packed full of tips and techniques you can actually use. Unlike many "self help" books, which is just the author explaining just how wonderful they are, without actually teaching anything.
If you're into crystal healing, you're probably not going to like his opinions on this or his rant about junk medicine, but you should probably read it anyway.
Let's see now... telephone, sausage, monkey... easy peasy! And the old lady with the beehives and totem pole still lets me remember that long number. I have never been able to achieve stuff like that before.
Buy the book - for the price of less than two pints, you could develop the basis of enough pub tricks to win all the drinks you'll ever need!
