Something you never touched on is the possible trauma of reanimation, such as waking up to horrific nerve damage all over your body and feeling like you are submerged in acid. There was a good movie from 2016 called ReAlive that touched upon this, it's about a man who becomes something of a celebrity after being the first human to ever be reanimated, as he acclimates to his new life he accidentally finds out that he wasn't the first person to be reanimated - he was just the first to be reanimated successfully.

I was once a paying member of Alcor and actually was trained to be part of their standby teams (never had to take part in a preservation though). From a morality point of view, everyone I interacted with had understood the at best this was a long-shot of actually being revived. Most had the attitude of, well I'm already dead, so what is the worst that can happen? How one would adjust to a radically different society is a good call out. But most cryonicists are futurists and science fiction aficionados, so they might have an easier time adjusting. Anyway, nice well-balanced video.

[edwardhartmann]

I've actually read all of Alcor's public case reports, and I can definitely say a large number of them are actually rather depressing. To have any chance at a hypothetical future revival, cryopreservation needs to begin immediately at time of death, and be done perfectly. The number of times this actually happens is super low. To the point, even if we had sci-fi level medical technology and knew how to revive people from cryonic suspension, things have gone so wrong for most of these people that nothing could be done for them.

I have always found Cryonics as a modern form of mummification, but instead of preparing the body to go to heaven, they prepare the body to go to the future.

My OB hit my son's head during my c section, yanking him out roughly and damaging his brain in the process. He had a seizure seconds after birth and his heart stopped. He was rushed to a "cooling" bed, where they kept him (specifically his head) extremely cold. 50 degrees f. He went on to make a full recovery, the cooling thearpy saved his life and stopped the damage. The specialized nurses who ran the program called it a "reset button" for the brain. While not exactly "frozen" cooling/cold thearpy is not only here but being actively used. Still loved the video and your channel! Just thought I'd give you a first hand account.

I remember a creepy sci fi short story. It’s told from the point of view of a “grave” robber who loots suspended animation chambers, after civilization has collapsed. While the robber is breaking into the chamber the sleeping person wakes up and is killed by the robber. What I took away from the story is that you can’t expect the future to be better - it could well be worse!

I think the current state of cryonics is plenty ethical. However, the problem I find with cryonics is that you are freezing cells in hopes of bringing them back to life; the theory being that it's been used for sperm and egg donations. The sperm and egg cells in question we're not deceased when Frozen and where in fact still alive, wholel I've not done much research on the matter I believe the same is true with the hamsters in the experiment referenced. When humans are cryogenically frozen after death, the problem lie in the fact that they are in fact already dead. I think if humans were cryogenically frozen while still alive that someday the technology would become such that we could revive them and cure them of whatever ailments may have put them in an "deathy" state, but this matter becomes far more ethically muddled. For example, if one were to be diagnosed with cancer and wished to be cryogenically frozen until a cure could be found that would not put their life at risk the way current cancer treatments do, I believe we could cryogenically freeze this still living person and bring them back at the time the cure has been discovered, but to freeze someone and risk their death, should they not be able to be revived, is something that I feel a medical board of ethics would greatly disapprove of.

I want to know who pays for the revival since you have no idea of what it will cost to actually revive someone or to repair the issues that made the person expire? What keeps the family of the person on ice from taking their inheritance? What happens if the Cryogenics company goes bankrupt do they dispose of the bodies or transfer them to another company or facility? Why would a family want grandpa back to take the things people now own since their passing?

Just a few questions I've NEVER seen asked or answered.

That long dramatic pause in describing the weather in a corner of southeast London had me on the edge of my seat!

[ABrit-btce]

Surely someone old considering Cryonics is fully aware of how knackered their body is. I can see how preserving your consciousness makes sense but mechanically most people are a mess half way through their life.
Great video btw.

Fun fact: the microwave oven was discovered during those hamster experiments. Tom Scott interviewed the lead researcher here on his YT channel not too long ago.

I have acquaintances who knew someone who was a proponent of this and was cryopreserved when she died. I made the mistake of reading the case report, and it was one of the most horrific things I've ever read. It took me from thinking cryonics is a "maybe" to a "no way". Especially because so many of the flaws in the process were on full display, such as the struggle for Alcor representatives to get permission to begin the preservation process -- bear in mind that she actually lived close to Alcor's facilities.

Even if there were no delays, and I'm sure she understood what could have gone wrong, I felt more like I was reading about a corpse people are pretending is still alive get desecrated. I like to read and hear about weird medical stuff, but this was different.

Do not consider cryonics without reading the case reports and being okay with what could happen to your body whether you can be brought back to life or not, and that you will essentially make yourself into a very expensive, energy-intensive, and legally (and almost certainly actually) dead test subject. Consider that your friends and family may be able to read what was done to your body in awful detail if you do not care about your own corpse.

Two things to know:
1) When the body or the brain is vitrified, the internal stresses on it are pretty major. In the industry, it's referred to as "meatglass", and is particularly prone to cracking right through if knocked or even just a rapid change in temperature.

Cracked.

Right through the head.

2) The whole bodies are stored hanging upside down with the head in a bucket. That way, if the power goes out or the liquid N2 starts escaping and vapourising, the last of the liquid runs down into the bucket and at least the head stays frozen the longest.

I have a friend who worked on the Timeship for a while many years ago. (A long-planned and never Actually built rival to Alcor)

I got morbidly fascinated by this topic for a while more than 20 years ago after reading Peter James's novel 'Host'. He did a LOT of research for it, and the science and processes were very well described/explained in the book. I still re-read it every now and then: it's well worth a read if this subject interests you!

[junkbot]

I really enjoy how he tells us about the weather. There always seems to be a pause, like he's looking out some window to check. "In a currently... average cloudy Southeastern corner..." I like it a lot!

I remember a Larry Niven story where they were called ‘Corpscilces’ and when they were eventually solved they were an underclass of indentured servitude as the money put away had long been used up

A good way to get an idea of the damage that the ice crystals do to cells in living tissue is to think about the difference between fresh fruit and veg compared to frozen, then thawed. When it's fresh, it's still crispy because the cell membranes and cell walls that give the plant its rigidity are intact and, well, giving it rigidity. But when you freeze it, the ice crystals pierce the cells like microscopic daggers, shredding the cell wall (among other things) to bits. So when you thaw out those frozen veggies, they're all soft and floppy and have no more rigidity because of this damage. And likewise, freezing a human would cause similar damage by way of microscopic ice daggers tearing apart the cell from within (and without).

Literally every time I see one of your videos it peaks my interest no matter the subject matter you do a great job at making thought provoking and truly interesting content and it’s honesty what I’ve needed for like the last year and I appreciate it a lot

[swaggerdagger]

Imagine you get unfreezed but then you just wake up in the afterlife

[chrisakaschulbus]

For me it's not really that much of an ethical problem. As stated in the video, they agreed to the procedure.
While the feelings of the family are something to consider, it's not their body.
And if we were able to unfreeze and "start up" bodies i think we should do it. Great stuff to think about, very good video! :D
