This document discusses cryonics and suspended animation. It explains that cryonics involves freezing terminally ill patients in hopes that future medical advances can cure them. However, freezing risks damaging cells and tissues. New techniques like vitrification which uses cryoprotectants aim to reduce these risks by preventing ice crystallization. While small tissues and cells can be frozen, whole organ and body freezing remains unrealistic. Some believe that with future technology, entire humans could be frozen and revived. However, this has not been achieved yet. The document also notes that cryonics companies charge $125,000 for full body freezing and market to those wishing to be revived in the future along with frozen pets.
Cryonic presentation-final
- 1. Date “Suspended Animation” of living organisms GÖKCAN DEĞİRMENCİ - TEVFİK ONUR SEVİNDİK
- 2. “Mom, let’s meet in the future…”
- 3. The Cryonics Method to be Immortal ! The fact: At very low temperatures it is possible, right now, to preserve dead people with essentially no deterioration, indefinitely. The assumption: If civilization endures, medical science should eventually be able to repair almost any damage to the human body, including freezing damage and senile debility or other cause of death.
- 4. Terminally ill patients could be cryogenically frozen in “suspended animation” until a cure can be found.
- 5. But there are some risks… *The process tends to destroy vital cells when the body’s temperature is lowered, or when it is defrosted. *Once the water leaves the cell, the cell will become dehydrated and unable to function. *Water can even freeze before it leaves the cell.
- 6. How can we reduce these risks ? *Slow freezing - blood, stem cells, sperm, human eggs, and embryos. *Advances in cryopreservation - vitrification -The first technique, called natural vitrification, can be achieved by quickly lowering the temperature. -The second technique, artificial vitrification, relies on adding substances called “cryoprotectants” before the freezing process begins.
- 7. -Cryoprotectants reduce the temperature at which freezing occurs. In addition, they make the ice more viscous so that it doesn’t crystallize. !!! The risk is that the cryoprotectant can kill the tissue. :) The solution is that freeze only small pieces of tissue or individual cells not larger ones. !!! That’s why the dream of using cryogenic techniques to freeze large organs, such as hearts and livers, has always seemed unrealistic. :) Remove the blood >> slowly lowered the temperature >> thaw
- 8. Ultimately, if all of the organs, tissues, and blood of a human can be frozen and revived, wouldn’t it be possible to freeze entire people, and then thaw them out in the future?
- 9. The answer is YES! but only for the first part of the question :(
- 10. Because none of them have been successfully revived, the second part of the question remains a mystery. Theoretically, it’s possible that at some point in the future a method will be discovered, but at this time that method does not yet exist.
- 11. Would you pay 125.000 $ to get frozen ?
- 12. The prospect of freezing people and later thawing them out has long factored large in the American imagination. It's a staple of science fiction novels. It's been a plot device in numerous movies from Woody Allen's Sleeper to Mike Myers' Austin Powers.
- 13. But is cryonics, as the process is called, a viable business ? Eventually medical science will advance to the point that the frozen bodies of dead people can be thawed out and "reanimated"--cured of the original cause of death, be it disease, disaster, or old age. Until that moment comes,the least they can do is freeze people.
- 14. There comes the price $$$ CryoSpan's prices for a full-body freeze start at $125,000. Neurosuspension, where only a patient's decapitated head is frozen, costs about $60,000. Giving a new meaning to the term "life insurance," most customers pay by designating their cryonics company as the beneficiary of their policies.
- 15. Date Many of those who opt for cryonics have their pets frozen along with them. "If you come back in 150 or 200 years, you're not going to know many people, so it would be nice to have your pet around,"
- 16. “Who will you choose to have frozen with you ? ”
- 17. HUGE Market for Cryonics Yet the cryonicists are confident that eventually their business will prosper. "Every year two million Americans die, and maybe three or four of them get placed in cryonic suspension," says Quaife. "That leaves about one million, nine-hundred-and-ninety-nine thousand, nine-hundred-and- ninety-six people who need our services and aren't getting them.
