According to this article, The people of the small Greek Island of Ikaria have a life expectancy that is 10 years longer than any other part of the world. It is attributed  to the nutritious diet that the citizens have and the lack of influence that the outside world has on other places. With less environmental factors to harm it, Ikaria is one of the most geographically advantageous places to live a healthy life.

Scientists are always coming across new evidence proving that specific lifestyles, foods, and activities are what allow some to live longer than others, but maybe we need to look at life length at a geographic level. These places where people live longer, healthier lives must have some common threads linking them. It could be similar cultural constructs that are endemic to these places, promoting healthy habits, a sense of community, and overall peaceful lifestyles. 

Oddly enough, most of his daily routines, such as drinking tea, using local honey, drinking wine, and leading an active lifestyle, are touted by different scientists and salespeople as to keys to longevity. I think, that these routines combined with a great sense of community, lack of stress, and happiness lead to long life. The community on this island is very close knit, and many people live happily. 

I really believe that the clean air of this island could have something to do with the life expectancy being higher.  The less toxins you breathe in the less of a chance you will have to developing cancers and other diseases.  

Now as to how this gentleman defeated lung cancer after moving from the U.S. to Ikaria is a whole other story.  Maybe the wine did help.  Maybe leaving a dirty and toxin-ridden environment helped kill the cancer.  Bare minimum, this article definitely shines the light on the air-quality in certain parts of the world.
