Thanks for the link, that was interesting to read. They link to a "medical report" from one of the cryprofreeze companies, about three people who were transferred from being frozen completely to just having their heads preserved (apparently this is a thing).

It contains such gems as describing said process of decapitating a corpse like this:

The patient was removed to an isolation tent with specially constructed supports, where a rapid conversion to neuropreservation was done using a high speed electric chain saw.

They go into some detaile about how the bodies reacted to being frozen for years and then warmed up again, which is interesting to read (for me at least) and shows that the technology needed to revive these souls is a long long time away (if at all)"
