有个笑话说,某医生从他的职业角度发现,人的周围,包括人本身,到处充满了细菌,在显微镜下看,各种形状的细菌到处在“蠕动”,叫人真恶心。就连吃的东西上,哪怕洗得再干净,细菌的数量也触目惊心。于是,这个医生什么也不敢吃,活活饿死了。 虽然这是个笑话,却是实话。微观世界,让人感到惊讶,也让人感到可怕。 There is a joke that a doctor from his career point of view, people around, including people, full of bacteria everywhere, under the microscope, all kinds of bacteria in the shape of “peristalsis”, people really disgusting. Even eating something, even if washed and then clean, the number of bacteria is shocking. So, the doctor did not dare to eat anything, starved to death alive. Although this is a joke, it is true. Micro-world, people are surprised, but also make people feel terrible.
