Brain transplants.
Perhaps into a cloned body.
You may laugh, but this one actually seems at least within the realm of possibility. I wonder why it is never mentioned.
Probably because hysteric bio ethicists would get a bit more hysteric, and somehow somewhy there are people who listen to them.
It's a great idea; currently impossible but maybe with enough research, the complications in the procedure could be solved. Then the real problem would be how long the old and frail brain would last in the young body. The procedure, if successul, could give the person a few extra decades (in the case he didn't die of old age) but not much more than that unless we learn how to keep the brain young.
This is an interesting piece of news, published in the New York Times in 1982 (which makes us imagine how far would we have perfected the technique if we decided to give it some attention instead of listening to the hysterical bioethicists):

Published: June 18, 1982
A piece of brain has been successfully transplanted from one mouse into another, where it not only survived but also correctly hooked itself up and functioned almost normally, a New York scientist reported at a conference here.
''This is what I call my science fiction experiment, except that it works,'' said the scientist, Dr. Dorothy T. Krieger, chief of endocrinology at Mount Sinai Medical Center in New York City.
Although the partial brain transplant succeeded in seven out of eight attempts with mice, Dr. Krieger said, she declined to speculate on any possible application of the procedure to humans, cautioning that it was only the first experiment.
The findings of the research, the most dramatic ever done with such transplants, are to be described this month in the British journal Nature. Dr. Krieger discussed the project in an interview Wednesday at the annual meeting of the Endocrine Society.
She said the transplants involved a specially bred strain of mice that produces both normal animals and some mutants that completely lack a crucial substance called LHRH, or luteinizing hormone releasing hormone. LHRH, which is produced in the brain, controls production of yet another set of hormones, the gonadotropins, which affect development of sex organs.
In the transplants, she said, the part of the brain that normally makes LHRH, a piece smaller than the head of a match, is taken from the donor brain and dropped into a natural cavity of the thimble-size brain of the adult mouse.
''Then,'' she said, ''we just leave it alone.'' The brain cells grow in the cavity, which is near their normal location, and begin to send out nerve fibers that hook up with the rest of the brain.
''Somehow,'' Dr. Krieger said, ''the nerves know just where to grow, and they make the right connections.''
The whole brain doesn't need to be transplanted; just the part responsible for the person's consciousness, memories, personality etc. The mechanica parts, the one that mechanically take care of the body, wouldn't necessarily need to be transplanted to maintain the person's sense of continuity.
