This book is GREAT it is full of mind stimulating activities etc that are designed to stimulate the brain. There are visual illusions and braintwisters and verbal puzzles and many other activities. I have not seen another book like it. It is engaging and stimulating and easy to read. A book that you may not want to put down - ofcourse you have got to be in a mood to do it, but once in a mood you wont be stopped.... I think of it as a type of GAME FOR ADULTS.
