Cryopreservation is an advanced technical procedure that uses extremely low temperatures to stop all biological processes in the body. Cryopreservation is not freezing, as the formation of ice crystals would be very damaging to the body. This procedure involves the use of specialized cryoprotectant solutions (think medical grade anti-freeze) to prevent freezing when the patient reaches sub-zero temperatures. Patients are cryopreserved in the expectation that future technology may be able to revive them and treat their underlying cause of death.

While research is constantly progressing, it's currently not yet possible to revive a human after they have been cryopreserved, but there is no fundamental biological reason why revival would not eventually be possible. Here is some what's currently possible with cryopreservation:

For decades scientists have been successfully cryopreserving and rewarming parts of the body such as embryos, sperm, and skin.

Scientists have also been able to cryopreserve a rabbit’s kidney which became fully functional again after it was rewarmed.

Research in 2016 showed that a rabbit’s brain remained in near perfect condition after it was cryopreserved and rewarmed. The synapses, cell membranes and intracellular structures remained intact, showing that cryopreservation can protect everything associated with memory and learning.

Scientists have also been able to cryopreserve and revive whole model organisms while keeping their memories intact.

€50/month (or € 500/year) and pays for technical equipment, training and maintaining standby teams on call 24/7. The Standby & Storage depends on which funding method you choose: €200,000 for whole body cryopreservation and €75,000 for brain-only cryopreservation. Most members choose to cover the cryopreservation costs with term life insurance which cost depends on your age and medical history. Both fees are paid for while members are still alive, nothing is paid after the patient has been cryopreserved. It is mandatory to pay the membership fee if you want to sign up with Tomorrow.bio, however you do not have to use our term life insurance option for funding - you can use an alternate funding method (e.g. own insurance, savings plan, will etc.). Please reach out to us if you would like to discuss alternate funding options.

Cryopreservation is maintained with liquid nitrogen (which is naturally at −196 degrees celsius in liquid form). No electricity is used, which secures patients against power outages and makes long-term maintenance economically feasible. The largest portion of funds are given to a patient care trust called the Tomorrow Patient Foundation (TPF). The TPF puts the cryopreservation funds into very low risk investments that have an annual return of 1-2% above inflation. The 1–2% return covers the running costs of maintenance (such as liquid nitrogen). This ensures that there are always enough resources to keep patients cryopreserved indefinitely, for however long is necessary for revival to be possible.

Given that the revival of cryopreserved patients requires significant scientific advancement, it's not possible to say if and when revival will be possible. However, there is no fundamental biological reason why revival is not possible. And the good news is that there is no time limit to how long you can be cryopreserved without degradation!

First of all, in almost all cases, you would not be saving money by waiting to sign up. For example, if you wanted to get term life insurance that covers you until 70 years old, the overall price difference between signing up at 50 vs. 30 is less than 1%. Signing up early means you can get significantly more years of coverage for almost no price difference. Additionally, if you were to develop any medical condition while waiting to sign up, you could become uninsurable. This would make cryopreservation more difficult and potentially expensive to finance. Another reason it’s better to sign up now rather than later is because it secures you against an early death. Even if it’s unlikely, there is always the possibility that you get a life-threatening illness or get into an accident. Signing up now is the only way to ensure that you can be cryopreserved, regardless of when you pass away.
