From Dan Buettner, blue zones discoverer, Miami Beach, Florida, US
Numerous peer-reviewed studies have validated the demographic origins of blue zones. The insights extracted from these longevity hotspots have created principles that have helped people live longer, healthier lives for a quarter-century. Claims to the contrary insult the science of demography and the people of blue zones, who are very proud of their culture of longevity (8 March, p 30).
