Blood Types And What The Hell They Mean

This is not my own writing, but something copied from the internet. It's apparently why the Koreans are so geeked about blood types. There's even a popular Korean movie called "My Boyfriend is Type B." Sounds like a John Hughes kind of thing. Hope you enjoy. Update: I can now keep solid foods down. Stomach is still very sore though.


History
The discovery of blood types in 1901 has been hailed as one of the greatest advances in medical history, but the breakthrough was then perverted by the Nazis to further their eugenics program, and claim the superiority of Germans -- mostly types A and O -- over Jews, Asians and others with a larger proportion of type B blood.
The theory reached Japan in a 1927 psychologist's report, and the militarist government of the time commissioned a study aimed at breeding better soldiers. The craze faded in the 1930s as its unscientific basis became evident. However, it was revived in the 1970s with a book by Masahiko Nomi, an advocate and broadcaster with no medical background.

Scientific support
While scientific study has shown that people of specific blood types may be more prone to certain illnesses, no medical evidence has been found correlating blood type with personality.

Character trait associations
According to Nomi's theory, those with type A blood tend to be reserved, punctual and law-abiding while type Os tend to be more outgoing and individualistic. Type A blood is the most common in Japan and Germany while type O is most prevalent in the United States. Interestingly enough, 60 percent of Japanese Prime Ministers have been type O. Type Bs also tend to make great cooks and restaurant guides featuring Type B chefs are popular products in Japan. In Japan AB blood type is often considered the least desirable type.
Persons having Rh negative blood types are extremely rare in the Japanese population, and generally the Japanese attach no particular significance to the Rh type.

Applications
Blood type theory is widely popular in women's magazines as a way to gauge relationship compatibility with a potential or current partner. Morning television shows feature regular blood type horoscopes, and blood type horoscopes are published daily in newspapers.
Casually asking one's blood type is quite common, and a refusal to answer may be construed as being ashamed of one's blood type. Some Japanese are frequently surprised if a Westerner does not know his or her own blood type.
The lack of proven correlation between blood type and personality has not slowed the many matchmaking services that cater to blood type (ketsu-eki-gata). There are even blood type consultants; who believe that they can calculate how well the blood types of different people work together - a Japanese employer could therefore aim to get a proper mix of blood types among their personnel.
It is also common among anime and manga authors to mention their character's blood types, and to give their characters corresponding blood types to match their personalities. Some video game characters also have known blood types, for example the manual for Final Fantasy VII reveals the blood type of Cloud Strife to be AB. Many fighting games (such as Dead or Alive or Street Fighter) often list blood type of characters on bio pages or in the manual. The videogame series Gungriffon and Princess Maker allow for blood type as an option in their creation modes.
