Li Ching-Yuen: The Man Who Walked the Earth for 250 Years!

By his own account, Li Ching-Yuen was born in the year 1736 but some people claim he was actually born in 1677 in Szechuan, China. He died May 6, 1933 which made him about 197 or 256 year old. Either way, still mind boggling for someone to have lived that long.
Documents have been found about the Chinese government congratulating him on his 150th birthday and on his 200th birthday.
Could this be true? Is this even medically possible?
You may think that he probably looked shriveled and totally wrinkled as an extremely old man should be but those who saw him insist he had a very youthful appearance.
It probably has something to do with the fact that his diet all his life consisted of herbs, rice and wine. If this is true, we should all start eating only these three foods. Then again, would you want to live more than 200 years on earth? There is a reason why we only last 80 - 100 years.
