Cold does reduce metabolism, so I have heard "cryonics" may be possible, but not at vitrification temperatures. Apparently, they have to replace your blood with a biocompatible antifreezing blood replacement during the process as well, and your blood would be kept separately under different conditions. So it's basically chillogenics, more than cryogenics, and it could be used to preserve astronauts in long travels, but I doubt we would see technology capable of thousand years long cryopreservations in a long long while.
