      On average it’s roughly five litres, though it’s less in women than men. If you know how many kilograms you weigh, you can work out your rough blood volume using this site! https://reference.medscape.com/calculator/estimated-blood-volume
      Potentially related, someone once asked a scientist whether you could get drunk by drinking a drunk person’s blood. If you want to find out the answer, have a read of this (but whether or not you want to find out the answer *do not try this at home, school, or anywhere at all!*) https://what-if.xkcd.com/98/
