Today I was doing homework with a friend, and he was offhand like "how much blood can you lose?" (turns out he was doing anatomy)
"Not more than 5 liters. Because that's all the blood in your body."
"That's...not extremely helpful, and why do you know that?"
*To admit it's Wattpad or not to admit* *ends up trying to explain an entire fanfic in a single breath*
So shout out to @skzenie and Scream My Name (Lee Know), because that is the only reason I know how much blood is in the body. And really, I never even fact checked that, but I just memorized it. So it's true now. Deal.
