Amazing unknown facts about longevity

We're all trying to live a healthy life, hoping we'll get as much of it, as possible. It's written in our genes, it's an instict: self-preserving. Let's see some little known facts, truly amazing, about long life spans.

"And all the days that Adam lived were nine hundred and thirty years: and he died." (Genesis 5:5)

We don't know for a scientifically proven fact, if there is the possibility of living 900 years, but we can try to live healthy and happily.

  • The world record for longevity is held by a french lady, Jeanne Louise Calment, who has lived 122 years and 164 days. She wasn't doing anything special to keep herself in shape, only a minimum amount of physical activities, like riding the bicycle or walking. She claimed her secret to a long life is olive oil, which she was using on all of her food and also on her skin.

    She had "unhealthy" habits like smoking (she smoked from age 21 until age 117) or eating one kilo of chocolate per week, or drinking a glass of Porto wine.
  • There are some areas in the world where centenarians are not uncommon, due to a healthy lifestyle, as a study has recentley discovered. Two of these places are Sardinia and Costa Rica, where people have a high intake of calcium and iron, thanks to their daily diet, which includes cheese and fish.
  • The area that has the longest life expectancy in the world is Japan. It is believed the longevity of its locals has something to do with their daily menu, which is full of vegetables, fish, grains and dairy products.
  • The most longevive light bulb in the world (still functioning) is burning for 110 years, without any pause, in the Livermore-Pleasanton Fire Department
    "Nobody knows how it's possible. It's a 60-watt bulb and it's only turned on for about four watts, but nobody knows why it keeps burning ... We've had scientists from all over the country look at this light bulb," (Lynn Owens, chief of light bulb centennial committee).
  • The oldest living tree in the world can be found in Sweeden, in Dalarna province, and is 9550 years old.
  • The oldest Champagne in the world (only two bottles left) is the Perrier-Jouet 1825 Vintage.
