BEIJING, May 7 -- The world's oldest
professor, Nanjing's most elderly male resident Zheng Ji, celebrated his 109th
Born in 1900, Professor Zheng is widely thought to be
the world's most aged academic, according to the Jiangsu-based Yangtze Evening
Around 100 guests attended a birthday party in his
honour at Nanjing University yesterday, most of them were Zheng's students.
Zhu Changsheng, one of the organizers of the party
and one of Zheng's students, told China Daily: "Professor Zheng felt very happy
to have so many people come to celebrate his birthday".
Zheng told guests: "Maintaining a positive and
optimistic attitude and living in an active manner are the main factors
contributing to a long life." As the founder of anti-aging biochemistry in the
country, Zheng is one of the most famous biochemists and nutritionists in China.
He has accumulated valuable experiences in the field
of anti-aging studies.
When he was 100, Zheng published a book about
maintaining good health and enjoying long life.
Zhang Youshang, a member of the Chinese Academy of
Sciences who attended the party, said: "Professor Zheng insisted on doing
research and normal exercises after turning 100. He set a good example for other
professors in the universities. Professor Zheng's actions fully illustrate the
meaning of 'life lies in motion'".
In Zheng's book, he suggests the main cause of aging
is the failure of cell metabolism. Therefore, isolation from radioactive and
toxic substances and a healthy lifestyle are the main anti-aging factors.
Zheng spends his daily life in a strictly scheduled
way. He gets up at 5 am and goes to bed at 10 pm and has a detailed timetable of
activities set each day that he follows closely.
Born into a farming family in Sichuan province 109
years ago, Zheng graduated from Dongnan University (the former name of Nanjing
University) and attained his master degree and doctorate in the United States.
