Acouple in their eighties have found a 'fountain of youth' in China's northern Liaoning province, AFP reports from Hong Kong. Zhou Lianghua and his wife Li Guirong attributed their youthfulness to drinking water from a well which they discovered two years ago in their courtyard in Fuxing village in Pulandian, the Hong Kong based China News Service said. Zhou, who was balding, now has thick black hair. His wife's grey hair has also turned black, the agency said. The couple said they felt '10 years younger' and did not get out of breath climbing hills.
