Scientists believe that the antigen of type O blood is the earliest. They studied the blood types of many long-lived elderly people and found that there are relatively many long-lived elderly people with type O blood. People with type O blood have stronger resistance and immunity and are more likely to live longer.
Regarding the relationship between blood type and personality, a Japanese scholar first put forward the view that people with type O blood have stronger willpower, more competitiveness and bolder.
People with type A blood have relatively high blood viscosity, so they are more prone to cardiovascular problems. In terms of personality, they are introverted and conservative, and their temperament is mild.
Compared with type A blood, type B blood has stronger digestive ability and healthier stomach, but it is easy to get fat if digested well. People with this blood type are outgoing, positive, cheerful and optimistic. This kind of good mentality and mood is conducive to improving immunity and making it easier to live longer.
Type AB blood is between type a and type b blood, and can have the characteristics of both blood types at the same time. Giving priority to type A blood and giving consideration to type B blood is prone to mood swings and stress, but it is better than type A blood and its digestive ability is not too good.
Since the conclusion is drawn through research, it must have certain reference significance. Blood type may have a certain relationship with life span and personality, but it is not very related. You don't have to care too much about blood type.
There are many factors that affect a person's life span, such as genetics, daily eating habits, exercise habits, economic conditions, mental stress and mentality. To a greater extent, these are the important factors that affect life span. If you have bad eating habits, bad living habits and a negative attitude, you may not live long, no matter what blood type you are, but your life will be shortened easily.
