I downloaded this little ebook from Pixel of Ink and read it several weeks ago. There were suggestive reminders but nothing really new. At age 61, I thought I might discover something innovative or that I wasn't already doing. I do need to oxygenate more. (I'm trying to avoid saying exercise.) I try to make up for it with deep breathing which I'm sure isn't quite as helpful. Why is so hard to exercise? But I deviate - this book is about memory. If you read very much on the subject you don't need to read this one, but if you're just starting out then I recommend 21 Memory Tips.
