There are two very different questions hiding inside "who is cryonics for?" One is about temperament, the love of being alive and curiosity about the future that make someone want this. We answer that one in who is biostasis for. This article handles the other, more mundane and more frequently misunderstood question: who can actually sign up? Forget for a moment whether the idea appeals to you. The practical answer is that the door is far wider than almost everyone assumes, and most of the reasons people rule themselves out turn out to be myths.
So we will be concrete. Age, health, nationality, wealth: people disqualify themselves on all four, and on all four they are usually wrong.
Almost any adult, at almost any age
The single most common self-exclusion is "I am too old" or, just as often, "I am too young to think about this." Neither holds. Membership runs from students in their twenties to people well into retirement, and the procedure does not care about your birthday. What matters is that arrangements are in place before they are needed, not how many years you have already lived.
The one genuine constraint is that you must be a legal adult to sign your own contract, since this is a binding decision about what happens to your own body. Below that age, parents can arrange preservation for a child, but the default member is simply an adult who decided not to leave it to chance. There is a reason we argue that turning 30 or a health scare makes it time to act: not because those are deadlines, but because the cheapest, simplest time to arrange this is while it feels least urgent.
You sign up while healthy, not while dying
This is the point that reframes everything. Cryonics is something you arrange in advance, like life insurance, not something you scramble to buy from a hospital bed. In fact the entire model assumes you are healthy when you sign. That is what lets you fund it cheaply, and it is what gives our standby and stabilization teams time to be ready rather than caught off guard.
This is also why "I am perfectly healthy, so I do not need to think about this" gets the logic exactly backwards. Healthy is precisely when you can act. A serious diagnosis does not make you ineligible, plenty of members sign up after one, but it does make everything harder and more expensive. The relaxed time to do this is now, which is part of the cost of waiting.
Most health conditions do not exclude you
People assume cryonics is only for those who die "cleanly," and worry that cancer, heart disease, or dementia rules them out. For the most part it does not. The procedure begins after legal death regardless of what caused it, and the goal is always the same: cool quickly and preserve the structure of the brain.
What actually matters is not the disease but the delay, the window between death and the start of cooling, because that is the real race against cellular decay. There are genuinely hard cases, and we do not hide them; we lay out the real limits in in which cases can't you be cryopreserved. A long unwitnessed delay, a body lost or not recovered, or a legally mandated autopsy that disturbs the brain are the real obstacles, not the name of the illness on the certificate. Exclusions are the exception, not the rule.
Most nationalities, across borders
Geography is the next phantom barrier. Tomorrow.bio was founded in 2019 with standby teams based in Berlin and Amsterdam, and long-term storage handled by the non-profit European Biostasis Foundation at its facility in Rafz, Switzerland. That European footprint is deliberate, and we explain why it matters in why a European provider changes everything.
You do not have to be European to be a member. What changes with location is logistics, not eligibility: how fast a team can reach you and how a patient is moved across borders. Our biostasis ambulance is registered as a funeral vehicle precisely so it can cross EU frontiers without legal friction, and the broader machinery of logistics, red tape and transportation exists to make distance a solvable problem rather than a disqualifying one.
Funded by insurance, not by being rich
The most damaging myth is that this is a toy for billionaires, what we elsewhere call the ultra-rich-only fallacy. The headline figures do look large: whole-body cryopreservation runs around 200,000 EUR and brain-only around 75,000 EUR. Almost nobody pays those sums out of pocket, and the model does not expect them to.
Instead, most members fund the preservation with a life insurance policy, term or whole life, that names the provider as beneficiary. You pay a manageable premium over your life; the lump sum is there when it is needed. On top of that sits an ordinary membership, roughly 50 EUR a month if you are under 35 (reduced to around 25 EUR where there is genuine need), or about 500 EUR a year, with a roughly 9,999 EUR lifetime option. For students and people on low incomes there is a dedicated path, described in membership for students and low-income individuals. The structure exists so that this turns out to be roughly the cost of a gym habit, not a fortune.
So who is left out?
Honesty demands the short list of people for whom this genuinely does not work today. You cannot sign yourself up if you are not a legal adult. You cannot be preserved well if your body is not recovered, or if a very long delay or a mandated autopsy has already destroyed the brain's structure before cooling begins. And you cannot benefit if you never put the funding and paperwork in place while you had the chance, which is the entire purpose of a simple sign-up process.
Outside of those, the eligible set is close to "any healthy adult who decides to act." That is a far larger group than the cultural image of cryonics suggests, and the gap between the two is mostly made of assumptions nobody ever checked.
The practical answer to who cryonics is for is almost everyone who arranges it in time: most ages, most health conditions, most nationalities, funded by insurance rather than wealth.
