Say, like, six pints of other people's blood put in you. How long does it take for that blood to be replaced by your own? I mean, if more of the blood in you is someone else's than your own, surely if you got your blood DNA tested the next day, the other person's DNA would be more prominent, right?
I make no claims to know how blood and that works in any great detail other than the heart pumping it about and re-oxygenating it or something.
Anyhow, Google has failed me, so I turn to the medical experts on Board 8.
