· Since 1975 the Morishita Worldwide Longevity Regions Research Delegation has conducted in the regions of Caucusus, Hunza and Vilcabamba several times per annum.
· In 1984, we designated Xinjiang Uygur as the world's fourth longevity region.
· In 1987, we named the regions of Caucusus, Middle Asia, on the periphery of Pamir plateau (including Hunza) and the area extends for 8, 000km from east to west in latitude about 40° N “The Silk Road Lon-gevity Region”. And we presented of the results of our research at the 16th Natural Medicine International Symposium.
· In 1991, we have conducted on the spot research of Pama of Guangxi district. In the process, we designated this area as the world's fifth longevity region.
We proved that most longevitists of more than 100 years live along the Silk Road and have a lot in com-mon. That is, they eat unpolished grains as a staple diet and do not live far from the place of their birth. And they also eat crops they cultivate themselves. Life energy, the healthy condition of the earth revealing morpho-logically interdependent life pattern found in their living, has cycled in the uncivilized longevities.
