It is estimated that Dong Yong's grandfather, Dong Sanmu, died young, and Dong Yong's father, director, had a habit of making noise at night.

After all, Dong Yong's grandfather needs to work during the day, and at night, because Dong Yong's father, the director has to cry at least once every night, and sometimes even cry several times. Crying and crying and crying tired and falling asleep. Fell asleep, fell asleep, woke up, and continued to cry. So Dong Sanmu's sleep was serious...... Insufficient.

Because, Dong Yong's father, the director, cried at least once every night, and sometimes even cried several times. So the neighbors gave the director a nickname, "night owl" ["night owl" has many meanings. 1. Dialects refer to people who don't want to sleep at night and people who like to stay up late. 2. Dialect In some rural areas, night owl also refers to mice and rats3. Another name for dialect owls4. Night owls, in common sayings, are called people who like to stay up late5. The neighbors gave the father and director the nickname "night owl", which meant that the director would cry at least once at night, and sometimes even several times. Like an owl. It is said that the owl is quiet during the day, and at night, the owl begins to call. Because the cry of an owl is very, very similar to the cry of a child, the owl is also called "bitter amusement". "Bitter and annoying" means that the cry of an owl is very, very similar to the cry of a child, and it is very, very annoying to cry in the middle of the night. 】。

In addition, Dong Yong's grandfather, Dong Sanmu, is very painful for his son director (the pain here is the meaning of love). The sentence is called "I am afraid of falling if I hold it in my hand, and I am afraid of melting it in my mouth", which is Dong Sanmu's attitude towards directors.

So almost everything delicious was given to the directors.

Malnutrition coupled with "death from overwork" was the reason for the untimely death of Dong Yong's grandfather, Dong Sanmu.

Because in ancient times, farmers were very, very hard, but now there are machines for plowing the fields.

Some of the farmers in ancient times used oxen to plough the fields, and some of them used oxen?

Pulling a plough on a person's shoulders [A plow is a farming tool used to plough the land. It consists of a heavy blade at the end of a beam, usually tied to a group of livestock or motor vehicles that pull it, but also driven by human power, used to break up clods of soil and plough trenches in preparation for sowing. The plough in our country is developed and evolved from the plow. Initially, it may still be called "耒耜". After the ox pulled the plow, the plough and the plough were gradually separated, and the plough had the proper name of "plow". The plough appeared in the Shang Dynasty and is recorded in oracle bone inscriptions. The early plough was rudimentary. From the late Western Zhou Dynasty to the Spring and Autumn Period, iron plows appeared, and oxen-drawn plows began to be used to plough the fields. In the Western Han Dynasty, there was a straight plough, with only a plow head and handrails. In areas where there is a shortage of ploughing cattle, the "tread plow" is widely used. In Sichuan, Guizhou and other provinces in the minority areas have the real kind of plough. The tread plough is also called "plough" and "foot plow". When using, step on it with your feet to achieve the effect of turning over the soil. Song Zhou went to Fei's "Outside the Mountains: Answering the Terroir": the plough is shaped like a spoon and is six feet long. At the end of the crosswood, more than a foot of wood, these two hands are also caught. In the plough handle, a short handle is applied to the left of it, and the left county is also treaded. In the middle of the plough handle, a short handle is applied to its left side, and the place where the left foot is treaded, and the plough is tread for five days, and it can be used as an ox plough for a day, and it is not as deep as the plough in the soil. In the Sui and Tang dynasties, the structure of the plough was greatly improved, and the curved plough appeared. In addition to the ploughshare handrail, there are also more plow walls, plow arrows, plow evaluations, etc. According to Tortoise Meng's "Sutra of the Elderly", there are 11 parts made of wood and metal, which can control and adjust the depth of the plough. It is as long as 2.3 zhang, which is very large, and it must be pulled by two oxen. The Museum of Chinese History has a replica model of a Tang Dynasty plow. Its principle is used for today's machine-led mouldboard plough. Compared with the straight plough of the Western Han Dynasty, the Quyuan plough of the Tang Dynasty increased the plough evaluation, which can adapt to the different needs of deep ploughing and shallow ploughing; the plough wall of the Tang Dynasty was improved, and the plough wall of the Tang Dynasty was circular, which could push the upturned soil aside, reduce the resistance to advance, and could turn over the soil clods to cut off the growth of weeds. Go plough the fields.

When a man pulls a plough on his shoulder, he becomes an ox. And it's not just once or twice.

Therefore, the cause of death of Dong Yong's grandfather Dong Sanmu has a great relationship with "death from overwork".

Death from overwork refers to a worker who is in a working state that exceeds the average working hours and intensity of the society for a long period of time, and the normal work and life rules are destroyed, and the fatigue in the body accumulates and transfers to the state of overwork, which increases blood pressure and aggravates arteriosclerosis, and eventually leads to death.

"Death from overwork" is because the working hours are too long, the labor intensity is too heavy, and the psychological pressure is too great, resulting in a sub-health state of mental fatigue and exhaustion, due to the accumulation of heavy work, it will suddenly cause an acute deterioration of the underlying disease of the body, and the treatment is not timely and life-threatening, according to reports: about 10,000 people die suddenly due to overwork in Japan every year. According to the survey statistics of the World Health Organization, the prevalence of overwork deaths has been recorded in the United States, the United Kingdom, Japan, Australia and other places; The term "death from overwork" has only been officially named by the medical community in the past 15 years. Relevant data show that the five diseases that directly contribute to "death from overwork" are: coronary artery disease, aortic aneurysm, valvular heart disease, cardiomyopathy and cerebral hemorrhage. In addition, digestive diseases, kidney failure, and infectious diseases can also lead to "death from overwork".

It is said that "death from overwork" can be prevented in this way.

1. Work and rest according to the biological clock. The so-called biological clock refers to the circadian rhythm inherent in various organs in the human body. People should arrange their work and rest according to their own circadian rhythms.

2. Balanced nutrition for three meals. When we arrange three meals a day, we must have a variety of varieties and a balanced proportion between them. At the same time, on the premise of maintaining the principle of "balance", certain adjustments are made to nutrients according to the physiological characteristics of each age group, so as to better promote good health. Nutritionists recommend that all ages should eat chicken, beans, spinach, fish, strawberries, bananas, oatmeal, kelp, nonfat yogurt and other foods because they are rich in energy, which can help you avoid burnout injuries and keep your body's engine running efficiently.

3. Learn to take the initiative to rest. The longer the human body continues to work or the greater the intensity, the more severe the degree of fatigue, the longer the time to eliminate fatigue, and the active rest can not only protect the body from less or no fatigue, but also greatly improve work efficiency. Specifically, you can start with the following points: First, take a break before an important event. For example, before taking exams, competitions, performances, hosting important meetings, long-distance travel, etc., you should take a break for a while. Second, ensure 8 hours of sleep every day, and have a "whole rest" on Sunday, so as to play easily and happily, and lay a good foundation for the next week's intense and busy work. Third, make arrangements for the whole day, in addition to work, meals and sleep, you should also clearly stipulate the number, time and method of rest in a day, and do not change or cancel at will. After the last, pay attention to and take a good break from work, make full use of this short time to go outdoors, or take a deep breath, or enjoy music, so that the body and mind can relax.

4. Conduct regular physical examinations. Have an annual check-up, including an electrocardiogram (ECG) and other tests related to the heart, for early detection of hypertension, hyperlipidemia, diabetes mellitus, and especially occult coronary heart disease.

5. Combination of work and rest. Learn to regulate life, short-term travel, sightseeing attractions; Climb the mountain and overlook, broaden the horizon; Breathe in the fresh air, increase mental vitality and relax tense nerves.

6. Insist on reasonable exercise. Exercise regularly to increase energy storage, walk 4~5 times a week for 30~45 minutes each time, or engage in gentle outdoor activities for 30 minutes each time 3~4 times a week. For people who exercise regularly, muscle atrophy and loss of strength can be delayed for 10~20 years, and blood pressure can be maintained at a stable and normal level. Exercise can delay the aging of nerve cells and help waste products to be discharged, thus playing a role in preventing and fighting cancer. Long-term adherence to fitness running and freehand gymnastics will strengthen the body's metabolism and work ability.

7. Keep your mood comfortable. Psychological overwork – disappointment, anxiety, fear, depression, etc., can lead to exhaustion. When a person feels troubled, depressed, and anxious, his body's blood pressure and oxidation will decrease, and when the person is in a good mood, the entire metabolism will improve. Boredom, remorse, resentment, anxiety, and sadness are intrinsic factors that produce fatigue. Therefore, in order to prevent fatigue and maintain abundant energy, it is necessary to always maintain a happy mood, be a person with a wide range of hobbies and interests, and always maintain a positive attitude towards life.
