In America what he said is actually common lore about cryonics. There is a famous cryonics center in Scottsdale, AZ that caters mostly to individuals suffering from diseases we cannot currently cure, essentially "Fry-ing" themselves into the YEAR 3000!!!, in hopes we will then have the medical technology to heal them.

I have also heard/read over the years that due to the crystallization destroying cells in this process, it wasn't viable for resurrection.
Here is the part DH is referring to, from the
Wikipedia article on Cryonics:

Long-term cryopreservation can be achieved by cooling to near 77.15 Kelvin (approximately -196.01°C), the boiling point of liquid nitrogen. It is a common mistaken belief that cells will lyse (burst) due to the formation of ice crystals within the cell, since this only occurs if the freezing rate exceeds the osmotic loss of water to the extracellular space. However, damage from freezing can still be serious; ice may still form between cells, causing mechanical and chemical damage. The difficulties of recovering complex organisms from a frozen state have been long known. Attempts to recover large frozen mammals by simply rewarming were abandoned by 1957.
When used at high concentrations, cryoprotectants stop ice formation completely. Cooling and solidification without crystal formation is called vitrification. The first cryoprotectant solutions able to vitrify at very slow cooling rates while still being compatible with tissue survival were developed in the late 1990s by cryobiologists Gregory Fahy and Brian Wowk for the purpose of banking transplantable organs. This has allowed animal brains to be vitrified, warmed back up, and examined for ice damage using light and electron microscopy. No ice crystal damage was found.

Still, I'm pretty sure all of those people are dead. Thanks to the both of you for wasting my time.
