Probably about a month ago I tried to donate blood. I say try because I had to stop them because I thought I was going to pass out. I had never had a large amount of blood drawn before but luckily I am alive. I finally got my donor's card and I found out I have A Positive blood. I did some research and A Positive is the second most common blood type in the United States. Also I had no idea there was research done on what I should eat and how personality quirks I have because I am A Positive.
This article goes into detail on what someone should and shouldn't eat and other weird things I have no idea that could be dissociated with blood type.
What's your blood type?
