Blood groups


And sorry if someone has already posted it.

Here is an interesting article about distribution and prevalence of blood groups.

Peter D'Adamo: Blood groups and the history of peoples

I often heard that type B blood group was Asiatic. And that it was so uncommon in Britain that a spy was once suspected only on the basis of having this group.

The article also gives explanation for the prevalence of certain blood groups. Type A is more common in Europe because it gave some resistance against plague. I think it is not mentioned here, but type B provided resistance against cholera and typhus. Hence it is more common in Asia.

I find information about migration of Native Americans interesting as well.

Interesting about the possible higher resistance of AB to infectious diseases. I am AB- and neither I, nor any of the male line members of my family back three generations have had anything worse than a common cold in maturity despite exposure. Even the childhood diseases which one HAD to contract in times gone by were very mild.

In Japan, there is a belief that one can tell someone's personality from their blood type, and it is quite common for people to tell each other their blood type as part of trying to work out their compatibility.

And I'm sure naoma would remind us that it's also customary in Japan is ask one's age.

The more senior one is the higher they are rated in the hierachy of Japanese culture.

The Chinese zodiac tends to be more popular, but you do get western astrology there as well. But the blood type thing is, as far as I'm aware, unique to Japan. Read this article:
BBC News - Japan and blood types: Does it determine personality?

There was an anime or manga, I don't remember which, that had a storyline derived from, or similar to, the Third Wave teaching experiment (
The_Third_Wave The_Third_Wave
) where students were encouraged to discriminate based on their blood type, to demonstrate how a segregated society quickly descends into fascism.

So as a type O, who would I be most compatible with?

May I point out that the BBC article linked here and the research article in the OP are at odds about the distribution of the blood types across the world.

Supposedly, O is the best blood type. You're compatible with O and AB. Here's what Os are supposed to be like, but I'm not convinced it's entirely accurate for you.

"People with blood type O people are outgoing, energetic and social. They are the most flexible of the blood types. They easily start up projects but often have trouble following through because they give up easily. They are flighty and not too dependable. O types always say what's on their mind. They value the opinion of others and like to be the center of attention. Also, people with O blood are extremely self-confident."

It doesn't seem too far off. The map shows around 15% B and 25-30% O in Japan, the article says 20% N and 40% O.

I'm 0 negative, and only use I had from it is many calls from local hospital to donate blood. Well, at least after donation I eat tons of free candies and drink free juice
