一个多世纪以来,人类的平均寿命从31岁,已经提升到了今天的接近70岁,我们是如何创造出这样巨大的奇迹的?不是抗生素,也不是疫苗,更不是什么器官移植。而是了解了正确洗手重要意义。尤其是外科医生的消毒洗手,极大降低了手术患者的死亡率。美国科学家早就发现,每个人每只手上大约会有150种细菌,一双未洗过的手上最多的有80万个细菌!其中最多的是令人感染腹泻和肺炎病菌。实验证 For more than a century, the average life expectancy of mankind has risen from 31 years old to nearly 70 years old today. How can we create such a huge miracle? It is not an antibiotic, nor a vaccine, nor is it an organ transplant. But understand the importance of proper hand washing. In particular, surgeons disinfect their hands and wash, greatly reducing the mortality of surgical patients. Scientists in the United States have long found that each person has about 150 bacteria on each hand, up to 800,000 on a pair of unwashed hands, the most common being diarrhea and pneumonia.
