Rediscovered- oldest person in the world

I wrote a while back about another discovery of the oldest person in the world in Israel and now is 121 year old. However, stop the presses. In Kazakhstan a woman who has records to claim she is 130 has been discovered. Sohan Dosova remembers the time of Tsar Nicolai and the Red Army and has a Soviet Passport claiming she was born in 1879! This is difficult to determine the authenticity since I am skeptical of Soviet documents. It is also mentioned that in rural areas of Kazakhstan it is common to make up a date of birth. Well she certainly appears old.
About the only bit of wisdom about old age she proffers is to put butter in your tea.
