We are writing a book on the moral obligation society has to cryo-preserve everyone. Currently, the costs of End of Life medical treatments run up into the trillions for society and governmental institutions with unfortunately extremely frequent failures, Furthermore, if the outcome is a legal death declaration, the patient VERY SADLY becomes a corpse to be disposed off.
The technology of cryopreservation, however has come of age and evidence accumulates every day indicating that suspended animation is the way. In fact it is the route to come back after we have advanced enough to reanimate someone.
Now, In the context of an spiritually and morally evolved world where ethics and religion correctly affirm that human life is sacred, it is evident that society must quickly move to facilitate the true extension of life for everyone AND to lower its end of life investments.
