I added the cite tag to the statement: "...and does not need food or water". I do recall from somewhere that in fact sustenance is required in cryo although that probably from a discussion about the topic along time ago and quite possible wrong. Although to back up this point, the Survival guide mentions, "...bodies are kept safe and nourished in chilled cryovaults". The inclusion of kept nourished does suggest that they require something albeit just simple glucose. (see page 153 of the Avatar Survival Guide) --IWantheUltimateChange 12:24, July 20, 2010 (UTC)
