Ranking of the four major blood types: Type B has an average age of 77 years, ranking second, which one is the first?

The composition of blood is basically similar, but there are many tissue differences. Judging from the blood types of all people in the world, there are about 8 blood types, and the blood types aborted in each person come from our inheritance. The most common is the abo blood type, which is the four major blood types: A, B, AB, and O.

Different blood types also mean different types of red blood cells in the blood, so people with different blood types have different rates of disease.

For example, many people in life believe that people with type O blood are more likely to live longer, while people with type B blood have better physical fitness. So what is the basis for these claims?

Four blood type rankings: B average age is 77 years old, ranking second, which one is the first?

First place, type O blood

Type O blood can be carried to every blood type, and will not cause the death of the transfusion person "universal blood".

The blood viscosity of O blood type blood is relatively low, and coagulation function is the worst in all blood types. In addition, people with type O blood have a strong ability to secrete gastric acid, but people with excessive gastric acid secretion will experience nausea, acid reflux, damage to the gastric mucosa, and cause gastric ulcers and even gastric perforation. Therefore, we should pay attention to eating habits and try our best to pay attention to light diet.

As the most primitive blood type, people with O blood type have certain inherent advantages. They have strong blood circulation ability, can transport oxygen and nutrients to various parts of the body in time, and maintain the normal functioning of the body.

According to the research, the average life expectancy of people with O blood is above 87, which is the blood type with the longest life span among the four blood types.

Second place, blood type B

People with blood type B, because they are usually good at communicating with others, are more cheerful and optimistic, and have a longer life span. In addition, they have a better mentality.

The average life expectancy of such people is about 77 years old, ranking second, which is relatively long.

Third place, type AB blood

ABA blood and B blood fusion, this blood type appeared later, accounting for only 8% to 9%.

Compared with other blood types, AB blood type is very healthy. There may be some minor problems during the workday that are not related to itching and pain, but are not life-threatening.

According to research, the average life span of ab blood type is generally around 70 years old, which is not too short.

Fourth place: A blood type

Blood type A is one of the four blood types and has the shortest life expectancy, with an average age of only about 62 years.

People with blood type a have relatively strong blood, so they have a high risk of cardiovascular and cerebrovascular diseases. Then these people should adjust themselves. Usually pay attention to a light diet and eat less big fish and meat. In addition, they should also be careful not to get up immediately after the alarm clock rings in the morning. Usually, we should also develop a good habit of regular physical examination for early detection and treatment.

If you want to live a long life, you still have to do 5 points well.

The length of life expectancy is related to many factors. Good lifestyle habits, a healthy diet, quality sleep and exercise all affect life expectancy. Here are five things you should do if you want to live a long life.

High-quality sleep: 24 hours a day, one-third of the time is spent in sleep. Therefore, ensuring high-quality sleep is very important for health and longevity. In order to get high-quality sleep, first of all, it is very important to ensure sufficient sleep time. Secondly, the sleeping environment is also very important. The bed should be placed in a corner sheltered from the wind. Try not to get close to doors and windows. Regardless of the season, keep warm and avoid catching a cold. The most important thing is not to stay up late.

Quit Smoking and Limit Alcohol: The health effects of tobacco and alcohol are clichés. Cigarettes contain more than 1,000 toxic substances and 69 carcinogens. Smoking is harmful to the respiratory system, cardiovascular system, brain and reproductive system, and can induce various tumors. Tobacco causes short life, with a 50% risk of premature death. Smokers have an average life expectancy of 10 years less than non-smokers. Similarly, excessive drinking can cause irreversible damage to the digestive system, reproductive system and nervous system, and the occurrence of various cancers has a great correlation with alcohol.

It is not suitable to eat supper: eating supper before going to bed will inevitably increase the burden on the gastrointestinal tract, and the information of intense work will continue to spread to the brain, leading to insomnia and dreaminess. Over time, it is easy to cause neurasthenia and other diseases.

In addition, if you eat too late at night, some protein cannot be digested and absorbed in time. Under the action of intestinal bacteria, toxic substances will be produced. In addition, the peristalsis of the intestinal wall slows down during sleep, which relatively prolongs the residence time of these substances in the intestinal tract, which may promote the occurrence of colorectal cancer.

Food should be diversified: If the usual dietary intake is too single, the nutrition will be fully supplemented, which will easily lead to malnutrition, lead to various diseases, immunity and body operations will also be affected, which will be harmful to human health and reduce life expectancy .

According to relevant research, food diversification, eating more fruits and vegetables can help to supplement balanced nutrition, which can enhance human cancer prevention, reduce stroke, and thus prolong life.

In addition to eating more fruits, vegetables, and various meats, you must also eat properly, so as to achieve the purpose of dietary diversity and comprehensive nutrition, and reduce hidden dangers.

Appropriate exercise: Due to life pressure and fast-paced work and study, people cannot spare a lot of free time to exercise. But the risk of not exercising is high, which will accelerate aging and increase the incidence of cardiovascular and cerebrovascular diseases.

Life is about exercising. Exercise can speed up the body's metabolism and blood circulation, and improve the endurance of bones and heart muscle. Exercising for about 45 minutes a day, at least 3 days a week, will not only slow the rate of aging but also improve balance and grip. It is mainly moderate-intensity aerobic exercise, such as running, walking, playing ball, cycling, playing Tai Chi, and practicing yoga. Studies show that prolonged sitting can negate any benefits of exercise. Therefore, exercising is very important.
