The following appeared in Asbury Park Press’s website:
Legend has it that Li Ching-Yuen was 256 years old when he died in 1933, presumably of old age, causing people many years his junior to wonder what his secret was.
His Wikipedia entry says he worked as an herbalist, eating a diet that included goji berries, a fruit grown in China said to be high in antioxidants.
Neither Li's age nor the health benefits of goji berries have been scientifically proven. But 84 years after his death, we continue to search for food that might not let us live forever, but at least can help us not feel so tired all the time.
