Three Oxford academics have taken an unusual step — they are paying an American company to be cryogenically preserved in the hope that they may be brought back to life in the future.
Nick Bostrom, professor of philosophy at the Future of Humanity Institute (FHI) and his co-researcher Anders Sandberg have agreed to pay a US company to detach and deep freeze their heads in the advent of their deaths.
Their colleague Stuart Armstrong has gone a step ahead and opted to have his whole body frozen.Preserving the full body is technically more difficult to achieve and can cost up to £130,000, The Independent reported.
When the researchers are considered terminally ill, a cryopreservation team will wait nearby for a doctor to pronounce them dead.
A machine will then be used to keep blood pumping while the body is cooled and the blood stream is infused with preservatives and anti-freeze to protect the tissue.
If only the head is being frozen it will be detached from the body, before nitrogen gas is used to reduce the temperature to -124 C.
The patient is finally cooled to -196 C, before being placed in a vat of liquid nitrogen for storage at a cryogenic preservation facility, where the patients would be stored until technology advances far enough to revive them.
