Maybe death is just another disease that doctors will one day cure. That was the dream of Professor Robert Ettinger, who is the godfather of cryonics. First dreamed up by Ettinger in the 1960s, cryonics is the freezing of bodies in the hopes of one day being able to bring them back to life in the future. Of course, there is no guarantee that this will ever happen, but the dream is that medical science will advance to the point where this will be possible. Perhaps the idea is not so far-fetched considering that scientists have already revived a small microscopic animal in Siberia after being frozen for 24,000 years.
