	Ah, the famous Segal Beagle experiment.  It was a hoax inasmuch as
Paul Segal and associates created such a confused media blitz in the
late 1980's with their experiment that to this day most people apparently
believe that the dog was frozen.  It was not.  It was subjected to a few
minutes of hypothermic circulatory arrest, and revived.  Human
neurosurgical patients in fact routinely recover from much longer periods
of circulatory arrest than that dog did. 

	The reality is that cryobiologists are only now beginning to
have some success at cryopreserving *isolated organs* like hearts and
kidneys.  The practice of cryonics today leans very heavily on
projected future technologies (like nanotechnology) to heal injuries
that are not reversible by current means.  In cryonics, we hope
to improve this situation somewhat by adapting technologies developed
to cryopreserve hearts and kidneys, and apply them to cryopreserve 
the brain of terminal human patients.
