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 pounds, The Independent reported.
The group have set up life insurance policies costing up to 45 pounds a month in premiums that will provide the funds needed to preserve them upon their death.
When they 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.
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.
Sandberg told the Sunday Times that life with just a head would be limited, but that he hoped by that point the process could involve downloading his personality and memories onto a computer.
Bostrom and Sandberg have chosen the Alcor Life Extension Foundation based in Scottsdale, Arizona as the location for their frozen bodies to be kept.
