I recently read another of the author's books, Exercise and the Brain. I liked that book as I thought it was an interesting introduction to brain exercise and gave valuable information on how to determine what exercises may be best for you. When I found this book, I thought it would have more specific exercises in it and be more of a workbook than it is.
There's a lot of text that is similar or the same from that book into this one. This book does have some additional sections on various types of exercises but overall they were somewhat dissapointing.
I like that he gave some specific examples of exercises and explained why he thought they might be helpful. I wish there was more of this given the recent explosion of brain training games and apps as well as many physics, word, puzzle and code games/apps/books/sites available. Maybe guidance on which may be best for various age groups or experience levels could be included.
The crosswords at the end of the book didn't display properly in my Kindle edition. The game board and the solved board appeared, but no clues for filling in the blank board.
The numerical exercises section was not up to par in terms of the quality of explanation. Normally, concepts are explained in as non-technical terms as possible, which wasn't the case here. My dad taught various math courses from elementary to college age, so I'm familiar with having complex mathematical issues described simply. Also, this section didn't leave you with many ideas you could readily try, more research than should be required is left to the reader.
For the speed reading, I would've like a site, book, or app mentioned so that you'd be sure you were developing comprehension as well as speed and for more guidance on timing this.
I feel that this book should be two books or have two sections. One's more about learning what the exercises are about, what they can do, how to choose ones that are best for you, and an introduction to the concepts behind the various categories of exercises. The other would be exercises organized by category you can do without further research as well as recommendations for exercises you'd be getting from apps or games or sites. He could also make checklists so you could note what you're interested in pursuing or give example schedules of training sessions focused on specific areas and/or amount of time required. This would make the book be more usable, less overwhelming, and more organized.
There's some good stuff in this book as there was in the other one I read. There's some new (compared to the other one) information that is useful. But as currently constructed, it's sometimes too complicated or appears as a brain dump of everything he could think of relating to the subject. I received this at a free or discounted rate in exchange for my honest review.
