What if we told you there’s a man who knows the secrets to longevity; Dan Buettner is that man. His work, including the acclaimed book "The Blue Zones," now inspires the Netflix series "Live to 100: Secrets of the Blue Zones." This two-decade endeavour reveals unconventional wisdom from those with extended lifespans. Let’s look at what we can learn from this research and the man who has dedicated his life to revealing the secrets of longevity.
What are blue zones and what's the link to longevity?
The Blue Zones are regions around the world where people tend to live longer and healthier lives compared to the global average. These regions are known for having a high concentration of centenarians and a lower prevalence of age-related diseases. The five recognised Blue Zones are: Okinawa, Japan; Sardinia, Italy; Nicoya Peninsula, Costa Rica; Ikaria, Greece; Loma Linda, California, USA (R).
Now, let’s learn how these Blue Zones can teach you to live healthier and longer and improve longevity.
