Yep, so apparently, people put forth links between blood types and personalities!
Blood types: A, B, O and AB.
Mine's A and while reading these comics, I have to say.. I cannot deny it's depictions completely!!
Blood types comic is a very famous comic series made by Realcrazyman from Korea. (I got a few from the web, enjoy!)

Well, what do you think?

I don't know my blood type. Sad.

I'm B LOL

I get told my blood type about five times a year and never remember help.

i never knew blood types have personalities but i'm an O+ hit me up if you need any blood donated huehue

I don't know my blood type but I would have to seem I'm O type? That's the most common blood type in the world. It's also the universal blood donor! Lil fun fact for y'all.
