They want to understand why the Japanese islands of Okinawa are home to the world's largest population of centenarians, with almost 60 or its 1,3 million inhabitants living into their second century-many of them active and looking decades younger than their actual years.
Like weekend visitors on the summer ferry to Martha's vineyard, scientists and sociologists block the boats to Sardinia and Nova Scotia, Canada, to see why those craggy locales hide vast clusters of the superold.
(2) As well as studying these populations intensively to unlock their secrets. Scientist have also taken a hard look at the very old in the U.S., most notably in the New England Centenarian Study, led by Dr. Thomas their longevity. "I never took a drink". "I drank a shot of whiskey every day," -experts are trying to unravel and understand the biological factors that allow some people to reach 100 while others drop off in their 70s or 80s.
Researchers are particularly interested in determining which factors allow up to 30% of those who reach 100 to do so in sufficient mental and physical health: a whopping 90% of centenarians, according to Perls, remain functionally independent up to age 92.
(3) It is pretty obvious even non-scientists that how you get their depends partly on the genes you are born with and partly on lifestyle-what and how much you eat, where you live and what types of stress and trauma you experience.
How much depends on each factor, through, was unknown until Swedish scientists tackled the problem in 1998.
They did it by looking at the only set of people who share genes but not lifestyle identical twins who were separated at birth and reared apart.

If genes were most important, you would expect the twins to die at about the same age.
In fact, they do not, and the average difference convinced the scientists that only about 20% to 30% of how long we live is genetically determined. The dominant factor is lifestyle.
