Question 1: How long can people live without food and water? A draft game of CCTV4 is called "Extraordinary Teenager", and one of the questions asks "How long can people live without food or water?" Choose the answer, 7 days, 30 days, 90 days. The correct answer of CCTV is 90 days. So I asked myself, how long can people live if they only drink water and don't eat? If you ask a doctor, if he is knowledgeable enough, the answer is four to six weeks, but the question is not that simple. Some doctors and psychologists have actually studied this problem seriously, but because no volunteers stand up and say (the parents of volunteers are unwilling), many of them are the result of speculation. Psychologists say that how long a person can live without eating or drinking depends largely on his willpower to live. For example, Xu Yunfeng and Jiang Jie can live for a long time. Indian Mahatma Gandhi went on a hunger strike for three weeks in the 1970s, and some people who didn't want to live could end their lives in less than two weeks. So in this extreme situation, how long people can live, people's desire to survive can play a great role, but it is not a decisive factor. The decisive factor depends on the person's health and obesity at the beginning of the hunger strike. Three days before the start of the hunger strike, glycogen stored in the liver began to break down into glucose to provide energy for the body. After three days, the glycogen in the liver is exhausted and the fat stored in the body begins to be consumed. At this time, the advantages of fat people are revealed, and how fat lasts for a long time. This is why people advocated obesity in the past. When the fat is exhausted, people begin to consume muscles, increase the degradation of protein, and use oxidized amino acids to provide energy. At this time, people will become very sick, have a headache and dizziness, and become extremely weak. Organs in the body will fail one after another. Hunger strikers have had examples of kidney failure, and then death will come. For the average person, this time is about 4 to 6 weeks. Of course, there are many variables here. For example, a person's own metabolic level can also play a great role. People with hyperthyroidism live many days less than those with hypothyroidism, because the basal metabolic rate is too high and energy consumption is too fast. Big fat man, who only drinks water and doesn't eat, is said to live up to 25 weeks. Some terminal patients can hardly last for a few days. I remember it was reported in the past that several students were traveling in the mountains and fell into a cave. A month later, people found these people. Only one person was alive, because there were some chocolates in this person's pocket. This person lived for 30 days on the water and chocolate in the cave, but he had multiple organ failure, and others could not live for 30 days. Experiments in this unexpected situation prove that people can only live less than 30 days in fear and despair by drinking water without eating. But there are exceptions I remember a few years ago, an old Sichuan doctor of traditional Chinese medicine lived for more than 200 days by drinking only one kind of "liquid" every day in a cage. He is still very healthy. I guess this liquid is similar to something to eat, such as pearl jade white jade soup. Someone asked, how long can you live only by drinking beer and not eating? I don't know. Some qigong says that it can "break the valley" for n years. Without strict textual research, I still believe in the law of conservation of energy and the law of physiology. At the present level of evolution, the human body has not been able to turn air into bread.

Satisfied, please adopt.
