Japanese people may have gained longevity by balancing their diets

TANAKA KANE is one of humanity’s great outliers. On January 2nd she became the third person ever to turn 118, according to the Gerontology Research Group, a team of academics. She is also the first citizen of Japan to reach 118—but is unlikely to be the last. The country has the world’s longest life expectancy, and 80,000 centenarians.
