Chinanews, Guangzhou, Jan. 24 – “Women live longer than men because they often cry,” said Wan Chengkui, a senior health expert in China. He gave a lecture last Sunday to residents in Dongguan, Guangdong Province, teaching them how to live a healthy life and prevent cancers by using simple examples in our daily life, Guangzhou Daily reported.In his lecture, Professor Wan said that generally speaking, women’s life expectancy is 5-7 years longer than men. Once they meet something unpleasant, most women would release the anger by crying, and it is crying that helps them to live a longer life.Related medical studies show that our tears, stimulated by emotions, contain a lot of poisonous elements. If one cries, the poisonous elements come out of one’s body through tears. He said that crying does no harm to people. However, it should be remembered that every time one cries, it should not last for more than five minutes.According to the professor, most of the factors related with a healthy long life are actually controlled by people themselves. If one often loses one's temper, one can easily get diseases such as vascular sclerosis, heart disease or high blood pressure. Those who easily get angry and do not vent their anger are most vulnerable to cancers. He said that most people die of their own living habits. So it is one's bad habits, rather than some natural disasters, that affect one’s longevity for most of the time.The professor said that if one wants to live a longer life, one should learn more information of how to live a healthy life. The earlier one learns, the more one will benefit, he said.
