How much blood do people have?

If you drained a human, how much blood would be in there? How much can a person lose before they pass out/stroke/die?How much blood do people have?
eight pints. after you lose three you'll pass out, more than that, bye-bye
Too much! Ten pints of red blood in total. People die long before their last drop is gone.
I guess maybe, your thinking about trying it. Dont. Its not easier that way.
LET IT OUT. The best song. True too xD
We all have about two 2-liter bottles of blood running through our bodies.
