There’s definitely beneficial information in this book and the progression across the aging continuum makes sense. But overall it’s pretty poorly written. For example, on more than one occasion a definition includes the word its defining. Like, huh? Expanded theories can read like utter word salads. Multiple times I turned to Google to track down the same information in a coherent and accessible format. My theory is this is such a tedious text to craft that no one else wants to actually write it and, thus, we have this mediocre product as the only option. Oh well.
