I do carry an organ donor card myself, and I've also given blood (which is still donated free in the UK) about 26 times. On my donor card I cross out the part that says "or any part of my body can be used for the treatment of others."
I'm quite happy to know that my "kidneys, corneas, heart, lungs, liver and pancreas" will go to help someone else. My brother's organs all went to help different people after he died, and it somehow makes his death a little less senseless to know that. However, I also once lived with medical students for a year. I know that they took skulls home on the buses, and I heard other stories involving cadavers. I'm just not ready to let people do anything they want with my corpse. If the market model was introduced, I would certainly tear up my donor card as I would be against anyone making money from my body parts. Unfortunately, as Larry Niven predicted, supplies cannot expand to meet the demand under the present circumstances.
The hope is that we can artificially grow organs and tissue as I said in my first post, but there will still always be a haves and have nots scenario due to tissue typing and the costs. It will be a case of the genetic discrimination we discussed in the other thread.
