OMG, no, no no. :)

Have you heard of the EPR-CAT study? Where they cool gunshot victims to 10 degrees Celsius to give surgeons hours instead of minutes to bring people back to life? I.e. those people are essentially dead — their brains have no electrical activity, their hearts have stopped beating.

And cryopreservation research for transplantology purposes is essentially the same as cryopreservation research for long-term storage purposes.

The only reason we need cryonics is because medicine is not yet advanced enough to treat all possible ailments. So cryonics is trying to preserve patients who cannot be saved by modern medicine until the time when they could be saved.
