Real story
I went to a private school in a rural area for junior high school, where I met many classmates. Now many years have passed, and many people have stopped contacting each other. Time flies so fast, and suddenly we are already thirty and four. Among the classmates, there are two from the same village, one is tall and one is short, one is fat and the other is thin. Sorry, I only remember two people with the surname Xiao, and their names have long been blurred by time.
At that time, Shuimu Tsinghua Band was quite popular, and the two of them had similar looks and body shapes to them, and they were usually inseparable. Everyone is familiar with them. Although their results are not good, they can bring us a lot of joy. We slept in a big dormitory, and the tall man had protruding teeth that couldn't fit together during normal times or when sleeping.
Once I was in a biology class . When the biology teacher mentioned the mouth, he said that if the mouth cannot be closed for a long time, sudden death will be more likely. We all looked at him angrily and teased him a little worriedly, but for rural children, who would pay too much attention to this? Few people care whether they keep their mouths shut when sleeping, but more about leaving an impression on knowledge. After
came to Beijing to work, one day I received news from an old classmate saying that classmate Xiao had passed away. I was surprised and asked the reason. It turned out that I came to Beijing with my classmates to work and died suddenly while sleeping in the middle of the night. I usually didn't feel any discomfort. The funeral arrangements have been taken care of, and it seems that he still has a wife and children.
After listening to the description of my classmates, I was shocked, and the words of the biology teacher came to my mind. But I still can't figure out the reason? Some say it’s because it’s easy for bacteria to enter, some say it’s because breathing is not filtered through the nostrils, and some say it doesn’t matter. I don’t know if any friends who are studying medicine can give an explanation or draw everyone’s attention.
