The Blue Zones
I recommend The Blue Zones as a basic primer on the principles that have enabled humans to live unusually long lives. The author, Dan Buettner, studied societies that enjoy unusual longevity, and he condensed what he learned from these societies into 9 principles for long living.
The Most Effective Ways to Live Longer
Here’s Dr. Jonny Bowden’s book on longevity. I am re-reading this one right now (May, 2013). For practical advice on longevity, this book is a very useful reference. Here’s what Dan Buettner, author of the Blue Zones (see above), had to say about The Most Effective Ways to Live Longer, The Surprising, Unbiased Truth About What You Should Do to Prevent Disease, Feel Great, and Have Optimum Health and Longevity (Sounds like upgraded living to me 😉 ):
“A must-read for anyone who wants to live longer! Jonny Bowden takes the lessons we’ve learned from the world’s longest-lived people and offers a research-backed formula for the rest of us to get the most good years out of our lives.”
