I genuinely can't believe some of the stuff I'm reading in here.
You're dead. You have no use for those organs. Give someone else a chance at life that needs it.
As an expert in dying how do you know that those organs have no bearing on what happens next?
FYI I don't believe anything happens (ie lights out and no more, heaven and hell are tosh etc etc) but some religions believe otherwise and nobody knows!
As for the back of the queue comments, thats really not how our society works or we wouldn't be treating criminals for anything.
