My step-brother is terminal because of lack of kidneys on the transplant market. He experienced chronic kidney failure at 14, and he waited over 20 years to the point his body is scarred from the repeated operations and prolonged trauma of going through artificial means which makes him unsuitable for further transplants, and has been on 'deaths door', for 5 years now, luckily still alive, due to wanting to force every once of life from his body continuing with painful measures.

I guess some people think organs magically appear out of no where like they do in Casualty.
