Reaching the age of 100, is a common phenomenon in certain parts of the globe. Among these places, named by researchers 'blue zones', are the islands of Ikaria (Greece), Sardinia (Italy), and Okinawa (Japan); the peninsula of Nikoya (Costa Rica), and the city of Loma Linda (California).
The explorer and writer Dan Buettner is the one who has popularized the term 'blue zones' through his books, articles, and lectures on the above locations.
There's no big secret or mystery behind this phenomenon of living to 100 and beyond. According to geographic and demographic experts - people in the blue zones owe their longevity to some or all of the following conditions: minimum pollution, no food processing, a relaxed way of life , sufficient exposure to sun, family and community support, faith, genetics.
In short, good genes, good habits, good environment, to which I would also add - a bit of good luck.
It seems to me that 'a relaxed way of life' is a tough one for us in the so-called developed world, as we're used to live in a "never a dull moment" scenario, with all sorts of slogans pushing us to "make a difference in the world".
Personally, I must admit that as I advance in age I feel I'm becoming more appreciative of those dull moments, of slowing down to doing almost nothing, of enjoying the small, simple pleasures of life. What I first have in mind is not the possibility of being a centenerian , but rather the prospect of living a life free of pain, dissabilities, and dependence that usually come with old age.
