I've read a couple of novels about the subject, neither of which has been translated. One was about a man accidentally frozen in an iceberg a few hundred years ago and his efforts to adapt to modern society. A sad story... The other one was about a scientist who was frozen in hope to get him cured in the future. He was the only survivor of those preserved: The freezing company had bankrupted and got unplugged from the mains after only a few decades. I suppose the latter would be the most probable scenario considering a time lapse of one or several hundred years.
There are many examples of people getting the said month to live. Yet many of them have lived long past their presumed dying day, some even for several years. For example the husband of my former colleague got a bad case of cancer and only months to live. He made a deal with his then teenage four daughters: He'd stay alive if the girls did their school well enough to prove they'd grow to self-reliant citizens. He hung along for six years, seeing his offspring graduate and get jobs.
I've also heard about a guy who got a whole year. He started doing things he had planned to do someday and when he felt that his end was nearing, causing him to become a vegetable at a fast accelerating pace, he arranged his own funeral party. A participant told me that the atmosphere was quite stiff at the start with the to-be deceased sitting there still going strong. After awhile the party got relaxed, folks memorizing how nice a guy he had been etc. I suppose the late would appreciate all the nice speeches much more during their last moments than six feet under...
