The ranking of the four major blood types may be announced: the average age of blood type B is 78 years old, ranking second, which type is the first?

There are many human blood types, and each blood group system is genetically determined and has immune characteristics. The most common blood type is the ABO blood type (divided into A, B, AB, O4). Followed by the Rh blood group system (mainly divided into Rh positive and Rh negative). Again the MN and MNSS blood group systems.

The blood group system is a combination of classifications based on the same heterotypic (or phenotypic) antigenic relationship on the red blood cell membrane. Erythrocyte epitopes can elicit the same abnormal immune response or abnormal immune responses. When identifying a person's blood type, a specific person's antiserum coagulation reaction is generally used.

Each blood group system is inherited independently, and the genes that control the blood group system are mostly on the same chromosome. Thirty-five human blood group systems have been discovered, but in clinical trials, the ABO blood group system and the RH blood group system are of the most clinical significance.

The ranking of the four major blood types may be announced: the average age of blood type B is 78 years old, ranking second and first.

Fourth place: blood type A.

People with blood type A are good at patience, and they often break out when they really can't bear it, so once they get angry, the consequences are often unimaginable.

People with blood type A are also most concerned about what others think of them, and cannot tolerate criticism from others, so they will try their best to gain insight into the situation around them and avoid making mistakes. Most of them are cautious and concerned. Even if they have a lot of ideas, they cannot express it smoothly because they are afraid of being opposed.

The third place: AB blood type.

Type AB blood is known for being calm, basically not angry, but when it occasionally loses its temper, it can be very scary. Because they control their emotions, the anger calms down quickly. While they want to save money, they also like to spend money. If it is not conducive to purchasing insurance, investing in bonds and other forms that cannot be withdrawn at any time, I am afraid it will be difficult to save money.

Second place: blood type B.

People with blood type B live a comfortable life and go their own way. Everything around them has nothing to do with them. They say whatever they want, regardless of the other person's feelings. They think that without money, there won't be many obstacles in life, and they don't understand why so many people are desperate to save. They don't care what other people think, so they can speak candidly to anyone, but Type B people are not good at explaining their views in front of many people.

First place: blood type O.

When people with blood type O focus on what interests them, they forget to think about the things around them. They are short-tempered and the little things can irritate them. They have a combative side to their characters. They basically don't keep silent when they have different opinions. No matter how boring the advice is, or how high the other person's status is, they'll be outspoken.

In short, no matter what kind of blood type, we must pay attention to develop good living habits and eat healthy food.
