Cryo-what-ifs


The search for immortality, youth, and prolonged life is made up and embellished in fiction, stories, television shows, and movies. We’ve seen it all from the magical flower in Gilgamesh to Rapunzel’s hair in Tangled to horcruxes in Harry Potter. It’s evident that we as humans are extremely concerned, or even obsessed, with living healthier, younger, and more beautiful lives. Some would go so far as to want to live forever.
Then it’s no surprise that with our increasing capability to alter ourselves with the help of medicine and technology and our insatiable desire to perfect and change our human form, we turn to transhumanism, science’s very own form of the fountain of youth. Transhumanism is the idea and growing movement that we can change human beings for the better, releasing ourselves from most of our natural inhibitions, with the help of technology. The most common forms of transhumanism include areas of anti-aging, DNA altering, robotics, and molecular manufacturing.
However, the area that most caught my attention was the field of cryonics, a technique used to store human bodies at extreme temperatures with the hopes of one day reviving them in the future. Branching from cryogenics, the study of what occurs at relatively low temperatures, cryonics is probably something that most people have heard of, or at least seen in science-fiction literature, film, and television. Though it may seem outlandish to some (after all, cryonics was even shown in an episode of SpongeBob Squarepants where Squidward is frozen in a refrigerator and later revived in the future), it is actually a process that is becoming more and more common and aspects of cryonics are already in use. With the help of cryogenics, doctors in neuroscience help prevent blood vessels from rupturing in the brain. Moreover, CPR and defibrillators are used everyday to help revive those who suffer from heart attacks. Alcor, one of the largest cryonics facilities, currently has two hundred patients and 20,000 potential candidates.


Cryonics....Squidward Style
            To quickly sum up the process of cryogenic freezing, once a patient is pronounced “legally dead”, a term here that means heart functioning has stopped but brain functioning still occurs, specialists work to remove quantities of water from the body and insert a type of anti-freeze to prevent cells from expanding and shattering. With a price of $400 annually and close to $150,000 total, companies like Alcor will preserve the body and its organs, allowing them to remain in this state of “cryonic suspension” with the help of liquid nitrogen for as long as it takes for technologies to catch up.
But what does catch up mean? That’s the other, more mysterious part of cryonics: we don’t have the technology yet, in layman’s terms, to unfreeze people without killing them. There has yet to be a case in which a human being has been “brought back” from his previous cryonic state. Scientists hope that with the help of molecular nanotechnology, or MNT, cell damage can be repaired during the freezing process. Keeping that in mind, potential candidates go in knowing that they will most likely “wake up” (if they ever do), decades to centuries from now. It is predicted that we’ll have the technology by 2040, though that’s just a rough estimate.
            With all this science and uncertainty in mind, why go through with cryonic freezing? To be honest, I wouldn’t go through with it. Even with the prospect of another life in the future, I can’t imagine living in a world without my family and friends. Nothing, in my opinion, is actually wrong with cryonics. I can definitely see the benefit in living longer or maybe even living better in the future. That’s one case made for cryonics: current incurable disease may find solutions in the future, allowing those living right now to potentially be cured and live healthier lives in the future. Apart from this reason, I personally don’t see any benefit to my life. There is so much uncertainty with waking up decades apart from your current state. No one knows the effects of living in a completely new world. I can’t even imagine the psychological and mental effects it would have, even if you were to wake up as a brand new, less human you. Moreover, would you really be willing to start another life without knowing anyone?
We have yet to see the implications of cryogenic technology. With its growing number of candidates and patients, it’s easily bound to be one of the leading technologies and fields in years to come. Though for some people, it may seem like a route to a different and improved life, for me and countless others, it’s complexity, confusion, and disorientation in the guide of perfection.

  1. First off, I don't know if it's just me, but your photo isn't showing.
    Secondly, I read about this kind of technology in Artemis Fowl, the second book of the series! As his bodyguard was dying, he froze him until he could get help from a fairy. Obviously, I'm sure cryonics doesn't quite go like this but similar enough.
    I completely agree with your view on this. It is an interesting technology to look at and it could "save" many lives but emotional aspect of waking up and knowing that everyone you know and love is long gone might be crippling. Even if you only freeze for another ten years and people are still around, you lost a good amount of time with these people, and the chance to make new memories with them. I think when choosing to take this option, the reason why should be carefully considered. If it's just to extend your time on this earth, it doesn't seem like a good enough reason.

  2. I feel like you explored cyronics quite nicely. This branch of transhumanism is certainly fascinating. It deals with philosophical issues, like you mention. Would we be the same human after hundreds of years of "sleep"? What does it mean to die and then come back to life?
    I wonder how religious people would view this process (other than the fact that it totally ignores God's power to take people to heaven/hell). Where is the human consciousness during the frozen state? And in that sense, what does it mean for consciousness to freeze and then come back to life?

  3. I agree with you in the sense that it would be completely disturbing to wake up in the future. But then again, wouldn't it be interesting to meet somebody who came from the past and learn about their reactions and opinion on his/her future, our present? Maybe we need some guinea pigs for that, and perhaps cryonics companies will make experiments like that one day. I enjoyed the fact you explored another aspect of transhumanism and did not stick to the three major themes we discussed in class of genetics, robotics and nanotechnology. This post was very nice to read and extremely well-written!

  4. Cryonics is such a controversial idea, and most people think that people who go through with it are nut cases. You detailed the process and the reasons quite nicely, and it reminds me of the movie "Vanilla Sky" with Tom Cruise. It also makes me wonder if it is just human nature to want to know what will happen in the future, and perhaps cryonics gives those who can afford it that solace that they might see the future. Also, on a more humorous note, I wonder when they collect your payment, is it like half to be frozen and half when you wake up? :) just a thought haha.
