We've got a living breathing example of a flatlined heart and completely inactive brain, frozen like a brick, yet spontaneously coming back to life.
Why isnt this the basis for suspension with humans? I can't imagine that our "hopeful" techniques would be considered more accurate and beneficial than completely copying what the Wood Frog does?
Why do we feel that our techniques are superior to a proven example that happens right in front of us?
"Special proteins in their blood, called nucleating proteins, cause the water in the blood to freeze first. This ice, in turn, sucks most of the water out of the frog's cells. At the same time the frog's liver starts making large amounts of glucose—a type of sugar—which packs into cells and props them up."
Obviously we lack the proteins, but the point is, why aren't we copying the methods and researching a way to duplicate this cell preservation?
