I’ve always thought that blood was kind of cool. Not in a weird, “I’m a vampire and want to drink your blood” way, butI’m always interested in learning more about the red stuff that keeps our bodies going. Truth be told, I am a little bit queasy when someone’s bleeding, but I still think it’s pretty cool — which is what brought me to today’s research.
I like to read about random things, like how much blood we have in our bodies and what it usually symbolizes. I wanted to share with you this excellent infographic with 30 amazing facts about blood. Don’t worry: These facts aren’t only science-based, so you’ll learn some historical and cultural things as well.
For example, did you know Ireland once had a tradition of giving away free pints of Guinness to blood donors to help them recover from any lightheadedness due to iron loss? Whoever killed that tradition made a huge mistake!
And during pregnancy, a woman’s blood volume increases by 50 percent. Just another reason to thank your mom for being awesome, I guess. In case you need a new hero, look no further than James Harrison, a man who has donated blood over 1,000 times. And I thought I was brave for reading research about blood!
