The Live Longest Compendium abridges the four previously published books 1. Newtrition 2. Successful Aging 3. What's Going To Kill You This Year 4. Slim 4 Life and adds in a bonus fifth book 5. Exercises and Physical Activity. While these original books have been condensed they have also been updated, their order changed and the title,"What's Going To Kill You This Year" chahed from "The Missing Keys'. They authoritatively cover the five fundamental basics for a healthy and long life, acessing the world's best medical studies but have been simplified to small, pleasant, achievable steps.
