      Erm – about 80?
      I know that i get a bit faint if i donate blood – and that’s only a litre.

      I thought it was about 8 pints in the average human body (I imagine it varies) which is about 4.5 litres.
      I always think that sounds like not very much…

      I have no idea, but I’m sure its not as much as many action films make out.
