I am really enjoying this book; it has lots of good common sense advice in an accessible format.
This book is more than a bunch of exercises. In fact, if that is what you want, you can find better books out there. For me, this book supplements exercise books I already have (not to mention tons of exercise information available to anyone online).
It covers a lot of general health related topics for men over 40 including diet, nutrition, stress, health checks, etc. It is well-written, concise, and easy to read. I like how the author provides information from studies to support many of the suggestions (granted, this is not a textbook nor a peer-reviewed scientific publication, so don't expect anything real well-documented. It would be easy enough to follow up on anything that didn't seem right).
I was skeptical and picked up my copy at the library, but I think I will purchase a copy to keep.
Bottom line: working out and eating the same way I did in my 20s no longer works for me. I am tired of trying to do my old freeweight workouts only to get injuries and still have a gut. Things change as you get older, and the sooner you realize what those changes are, the sooner you can move forward.
