The world asks: Why do Georgians live to be over 100? [VIDEO]

Japanese journalists are filming a documentary about Georgia’s elderly population and their longevity.

A journalist and cameraman from Tokyo TV are currently in western Georgia’s Black Sea coastal Adjara region, where the pair interviewed two women aged 111 and 105.

They were impressed with the "clarity of mind” and "strong eyesight” of the Georgian centenarians.

Georgia has earned a global reputation as home to the population with the greatest longevity in the world. Adjara is the area where the highest number of people aged over 100 lived in the country.

In 2012 Georgian woman Antisa Khvichava, who claimed to be 132 – and her age was confirmed by Georgia’s registry officials – died in Georgia. If her ID documents were real, she was the world’s oldest person. However this was not officially recognised by Guinness World Records before she died.

Meanwhile Georgians’ longevity was in focus of an American yogurt commercial filmed back in 1977. The commercial featured healthy senior citizens of Georgia who were filmed eating yogurt and living a long and happy life.

The clip stated: "Eighty-nine-year-old Bagrat Tabagua liked [the yogurt] so much he ate two cups. That pleased his mother very much.”

This was also the first American commercial filmed in the old Soviet Union.
