The author has done a fabulous job in writing this book for guidance to a better, healthier lifestyle! It's the perfect length! The 12 fixes are supported by scientific-based research and each of the 12 chapters correspond to the 12 fixes! Practical, clear and straight-forward to read! Each chapter ends with a short summary, and action plan (which I personally love because it inspires me to integrate them into my life... one at a time, so it's not overwhelming!) You don't have to read it cover-to-cover, but can jump straight into the chapter of interest or that is your current greatest need. Generally, we don't make changes until we have to, but why not care enough about yourself and your loved ones to make small, incremental changes NOW?
