Insufferable, tiresome, stubborn. It can't be helped, it's in my blood.

It’s interesting that in Japan there is a theory that blood-type dictates personality type. Here in Japan knowing your blood type is like knowing you zodiac sign, and just like being a Leo, being a person with O positive blood endows you with certain traits… apparently.

This came up in conversation the other day and a couple of people agreed with this theory enthusiastically, using the whole zodiac theory as a counter argument which could be easily discredited thus adding kudos to the blood theory. I however countered that more than blood and in essence ‘nature’, a person is the product of ‘nurture’ also.

we aren’t a product of nature alone, nurture and experience have more influence

By no means am I supporting a fanatically tabula rasa point of view, I think that philosophical theories like meme’s have sound arguments, but don’t know them well enough to quote them verbatim. But my point is, we aren’t a product of nature alone, it’s a combination and I think that nurture and experience have more influence on us than nature.

“blood-type” theory... eugenics... Nazi science

However, the most interesting thing about the whole “blood-type” theory in my opinion is the link between that and eugenics, or as I like to provocatively term it, Nazi science.

I wonder if blood-type is a factor in dating and has anyone ever been dumped because they had the wrong blood?

I don’t know which blood-type I am but from looking at the supposed traits I think that I’m either B or AB.

Conservative, introverted, reserved, patient and punctual. Perfectionists.
