Never understood the quest for immortality. We are the children of our time. When our time passes, we will live as strangers in a strange land, drowning in the sea of nostalgia. Death will simply takes us back to where we came from before our birth. Don’t fear the reaper.

I've lived as a stranger in a strange land and I regret returning 'home', whatever that means. Sounds like cryo is right up my alley! If it only worked...

I'm no believer in immortality, but I find your argument unconvincing. People are removed from their childhood home all the time, immersed in a foreign culture. They survive. I'd certainly accept a sudden relocation to an unfamiliar foreign land vs. dying. And I'm certain that a hypothetical resurrected human wouldn't be the only one - what's to say these folks wouldn't form their own pocket of culture?

It's in heliocentric orbit, it's getting cooked by solar radiation every day, taking the full brunt of solar flares without a magnetosphere to protect it, etc. If there were a body in the suit, it would surely turn into beef jerky. Or perhaps soup, if the suit can keep the fluids in. All the DNA would be shattered beyond repair by intense gamma radiation. > but makes a certian amount more logical sense than a dummy i…

One potential limitation of cryogenics is that the radio isotopes in your own body will eventually cause too much damage to your DNA since natural repair processes will be offline as well. Obviously the radiation environment in space is much worse.

That is a good point.

In case it's insightful, I've correspondingly never understood the common contentment with death. The world is an incredible place, and there's so much to experience and do. If I had the time there's hundreds of careers I could spend a lifetime in each trying to develop mastery. I think I could live a thousand lives with the people I care about and not be done. I've had to choose one life, and it's a nice one, but if it wasn't for some limit forced upon me, if it was really my choice, then there's a lot more I'd like to do.

I suspect in hundreds or thousands of years we'll look back at age-related death culturally the same way we look at infant mortality during the medieval ages: commonly accepted as part of life at the time, but unnecessary and completely solvable in retrospective.

I think fear is the wrong word per-say. If it's something I can't change, that's fine. But if there's an avenue to change it, even if unlikely, why not try?

I for one would like a bit more time. 200? Maybe 500? No one likely wants to be immortal but 80 or so seems criminally short for what our abilities are and how long it takes for us to find our calling.

We all die eventually, so far...

you'd figure if biology was capable then it would have found a solution by now. But as far as I'm aware immortality isn't a trait of any multi-cellular organism that has ever lived on this rock. I mean maybe we can stick some pipes in a corpse and get it to move around or make a digital echo of a dead personality and have that rattle around inside a robot. However, I feel like we're drifting into wishful thinking if…

Consider that death may actually not be as selected against in nature as you seem to imply. An everliving organism would not as easily adapt to a changing environment, if and until a new mechanism of evolution is generated. We may be stuck in a local minima.

Nature doesn't have goals. Humans, as far as I can tell, very much do. Put another way. Evolution didn't find a way to get life onto the Moon. Humans did.

> My understanding is that no one has been (intentionally, carefully) thawed after being vitrified using "modern" techniques, so we really don't know what condition a body would be in after unthawing using current technology. why haven't they tested this on animals or non-paying cadavers? It would seem unwise to pay to keep vitrified bodies frozen if one had no understanding of how the bodies would be when they were…

The state of the art in this field is removing a rabbit's kidney, vitrifying it, waiting a month or so, thawing it and implanting it. I haven't read this article but the abstract seems to confirm what I read a while ago.[0] Apparently the bottleneck is in thawing organs past a certain size, current thawing methods lead to uneven thawing in larger organs, however I read they were experimenting with using directed radi…

In the 1950s scientists were freezing small rodents and reanimating them using a primitive microwave. [0] If vitrifying and reviving a single rodent organ is the state-of-the-art 70 years later, I am not exactly impressed by their progress.

If I don't want to die now why should I want to die later?

The article refers to cryonic storage units as Dewars: The vacuum flask was designed and invented by Scottish scientist Sir James Dewar in 1892 as a result of his research in the field of cryogenics and is sometimes called a Dewar flask in his honour. While performing experiments in determining the specific heat of the element palladium, Dewar made a brass chamber that he enclosed in another chamber to keep the palla…

Or a warm beer and gazpacho.

I would love to know how this is handled in other parts of the world. Particularly the regulatory side because this is a potential health nightmare for OH&S if not the water table and the neighbourhood.

The escrow requirements for maintainance of state would be interesting too. Who exactly benefits from the spend? Is this contestable by a future generation? In effect, does the corpse become property?

Perpetual funding is a pretty bizarre concept, but that said the entire 'south sea bubble' debt exist inside British gilts for hundreds of years, they only wiped them out recently at the same time as the WW1 debt, so carrying forward into the future does happen, albiet mostly at scale by governments.

I guess if you turned the dewer flasks into a freak show and charged, you might even be able to fund the cooldown by revenue.
