Haha so why do you think Japanese movies make blood spew everywhere like a geyser?

I think its because Japanese people have high blood pressure

to make the movies seem funnier.

Loool! High blood pressure XD
Personally, I dont know, coz I dont really watch movies that involve blood and horror XD

Because Japanese people have powerful hearts that can pump the blood like this.
... This really creeps me out when you see the blood flying out of a cut arm!!! Ewwww~!!!

To make it more colorful
