Im sure it would be possible IF kept in optimum surroundings. But you got to think about other people. They could have inherited liver diseases, blood problems, cholesterol, you name it theres tons of them. Not to mention pollution from where they live, and what kind of activities that person may have/not been doing. And theres always the possiblity that the body could reject it =/.

As for the brain thing, once the person dies the brain dies aswell, so i dont think theres much hope on that. But thats just what i think, im sure im wrong.
