A fantastic song about cryonics (“the low-temperature preservation of humans and animals who can no longer be sustained by contemporary medicine, with the hope that healing and resuscitation may be possible in the future“). The BBC has a small gallery, “Frozen in time“, which is interesting to look at.
What I find amusing is that to be cryopreserved, you need to first be pronounced dead. It would be amazing if, in the future, we develop the technology to bring back people who have been frozen. The realms of science fiction would definitely become science fact at that point!
