Well,since majority of us here are long time kpop fans (obviously) 
We must at least have an idea of how blood types play a big part in Korea right? 
I mean,at first I was like 
"why do they even believe in these things?" 
So I read "All About TVXQ" and at the author's note she wrote about her blood type 
Coincidentally she has the same blood type as me ( I guess) 
Blood type B
I was surprised at how spot on these things are

So I decided to look up at her sources and read on 
I was even more surprised 
I mean come on,I don't believe these stuffs (just like the stars thingy.Picses,Sagittarius etc) 
but the fact it was so spot was just so.....amazing? 
It's kind of ridiculous how in resumes at Korea requires for you to fill in the blood type section
Blood type B people have a lower rate on being hired 
because of what? 
because of the bad luck Blood type B curse
Come on~ not every Blood type B is bad 

It's just fascinating to read how these type of thing effect koreans so much 
I mean I'm not insulting
It's just fascinating that how can a blood type can determine a person's personality 
Now I know why my dad's korean friend was so surprised when I said I'm a blood type B 
You guys can read it from here and here
