Bests & Worsts Reviews from Amazon

I am in my mid-60s. As a former competitive athlete I was seeing a lot of the normal, as in average person nowadays, degradations of my quality of life. Additionally, like many people, I’ve been spending a lot more time in front of a screen. By one or 2 o’clock in the afternoon, naptime. In the first week since buying the book I haven’t gotten sleepy mid afternoon. The book is well researched, a great read story wise, and contains valuable exercises. I can’t recommend this book enough.
