Based on cryopreservation through many novels and movies such as Vanilla Sky. One has the ability to freeze oneself under ultra-cold temperatures, making the aging process stop and non-existing which would achieve "suspended animation". Already there have been cases of this process, even companies like "www.alcor.org" is offering the service of immortality through cryogenics. Soon we can see if this technology can be harbored.
Soon I will achieve exactly what Tom Cruise acheived in Vanilla Sky, by purchasing life extension membership from Alcor.
