Human hibernation?

While this article does say that hibernation for the purpose of space travel to distant planets or galaxies is far off, it is definitely worthy of further research additionally for the medical field. It discusses some current hibernation techniques of animals and the physical processes involved, and also gives a few examples of people that had been revived after appearing to be dead in extremely cold situations. Even if hibernation for human application is as they say "decades away," so is human travel to Mars. If hibernation proves to be a safe and feasible endeavor before the mission to Mars project is fully underway, a lot of time and money could be saved with the relatively sparse materials needed to keep the crew alive for the flight if they were hibernating rather than active and awake.
