This book should pass the test of time, even if some of the specific treatments, routines and advice will likely be outdated in 5-20 years. The goal to live (and the methods to achieve) a rich and active life that you can enjoy in your 80s and 90s is something that most health books don't even consider.

The chapter about Peter's mental health made the book stand out amongst similar "here's how to be healthy" books.
