The first story is about my primary school teacher. He is the teacher who teaches our Chinese class. Every day, he goes to school early and then runs around the school playground for about half an hour. At that time, he was almost 50 years old when he taught me. He is deaf, deaf and energetic when he walks. Maybe many people think it's strange that you were deaf before you were 50 years old and had difficulty walking. But I can only say that you haven't met him. If you have met him, you will find that he looks like a man in his thirties. In addition to his gray hair, his physical function is even comparable to that of our physical education teacher who is less than 30 years old. The school organizes basketball games, and he is still the main force. According to our Chinese teacher, he has been running for almost 20 years.
The second story is about a relative of mine who is a little sad. Although running is good for health, his running style is somewhat unreasonable. In the early years, I only knew that running was good for my health, and nobody cared about my knee injury. Under normal circumstances, ordinary people can run at a moderate speed, mode and duration, but he is different. His prescribed route and running style are not quite right, and his habit was formed in junior high school, so he persisted for nearly 10 years. 20 17 he felt pain in his knee, but he was sure it was not rheumatism, but the kind that hurt when he ran fast. Finally, he went to the hospital for examination. The doctor said that the fragile bone inside his knee had worn out and he had to undergo surgery. Although he has had an operation now and recovered well, he can't run any more. Although his body got a good exercise because of running, after running for 10 years, his knee has been damaged, and some of it is not worth it.
The third story is about my junior high school classmates. I haven't contacted him for five years, and I don't know how he is now. No one may believe it. His academic performance is not bad, but he always sits in the last row of the class, and no one wants to sit at the same table with him. It is not that he has a bad personality, but that he is fat. He 180 cm tall and weighs more than 240 kilograms, occupying two-thirds of the desk. At that time, he also had excellent academic performance and academic performance. In a school physical examination, he was found to have some poor physical function, and the doctor even asked his parents to come. Later, I heard from our teacher that he had high blood pressure and severe fatty liver. If he is not treated or improved, he will easily suffer from other diseases in the future. In this way, he made up his mind to start running, panting from the first few steps, and running five laps in one breath was effortless. His weight has also dropped from 240 kg to 160 kg. Although it still looks fat, it has really improved a lot in all aspects. Now that we are all in our thirties, he has been in love with 10 for many years. He still keeps this habit and is very healthy.
In fact, I tell this story mainly to tell you that running 10 years is very helpful to your health, but at the same time, you should pay attention to your actual physical condition. Although you can exercise with the wrong running posture or inappropriate exercise methods, it may also damage other parts of your body. Please pay attention to this. But in general, people who can run for more than 10 years have really unusual physical fitness.
