Will it be possible for any human or living being to cheat death? Can Science ever progress enough to revive dead humans? or turning then immortal? You might be surprised to know that an American company is already working on this project. i.e. they're working hard on the formula to cheat deaths. The way designing of an air plane is called aeronautics, designing of electronic devices as electronics, And designing of robot is robotics similarly, the field of preserving dead bodies in hopes of resurrecting them is called cryonics. Experts are very hopeful that after 50 or 70 years medical science will be so advanced that it'll prevent people from dying Or even resurrect dead people, So far the science who wish to be resurrected after dying and have enough faith on medical science for them, there is a company named Alcor based in Scottsdale, Arizona. From the outside, it seems to be a pretty normal office. But at the centre of the building the scenario is kind of strange. There are 300 dead bodies in these big steaming containers made of steel. Also, 33 pet animals were frozen here in hopes of their resurrection. Here, death is not seen as we normally do rather, Alcor's team believes that they are also normal people just that their hearts don't beat and they're sleeping for a long period. Apart from that, every part of their body is perfect condition. We can also say that time has stopped for these 300 peoples for several decades. If medical science can resurrect them after 70 years then they will be resurrected in the future. As we have seen in science fiction movies like Time Machine/Time Travel. The temperature inside these containers is colder than the world's coolest place Antarctica. The temperature inside this containers filled with liquid nitrogen is -196°C. Which is being controlled 24x7 by computer, And backup generators are there in case of a power outage. A big container contains 4 full body patients and 5 neuro patients, i.e. patients whose heads are only preserved. This small container is designed only to freeze head and face. Out of 300, 116 patients have decided to freeze their heads in which their brain and all the data, memory inside it is 100% safe. Cryonics researcher believe that when they will be resurrected, their face and brain will be their own but their other body parts will be artificial. They will remember everything prior to their death and they will be able to use their brain as normal human beings do. Their artificial body will receive signal from their brain and their artificial heart will pump the blood as a real heart does. But the question is how all these will be possible? Cryonics is not that simple as it seems. Just putting the body into the liquid nitrogen will not work rather it is a full process and very costly. It costs $220000 or 1.65 cr rupees to cryo protect full body. And one has to pay $80000 or 60 lakh rupees before death for cryo protecting the head. After accepting the conditions when all the documentation is completed, then the patient's name is added to Alcor's waiting list. That means the doctors at Alcor started waiting for the patient to die. A remote team of doctors who are always on call for 24 hours, when they got to know the patient is about to die they started doing their special arrangements in the hospital. The patient is brought to Alcor's facility within half an hour of their death and procedure for cryo protection is immediately started. Experts believe that the faster this process is started after their death, the chances of their resurrection increases. By what is that process which is very important for resurrection? After death, the heart stops and thus the blood flow in the veins also stops. When the blood supply doesn't reach different organs then one by one these organs started falling. From death to the start of the cryo protection process. It is important to keep the blood flow intact in patient's body, So that the brain and other organs keep receiving blood. For that reason a mechanical pump is fitted to the patient's chest which artificially pumps blood to their body parts. But this doesn't end here after that the real action begins in the operating room. Here, all the blood is drawn out of the patient's body and a special chemical is induced instead of that blood. Now it is important to note that human body constitutes 60% of water. So if it comes in contact with liquid nitrogen then the water inside cells of the body will become crystals. And the body cells would break. And it would not be possible to repair them. Doctors at Alcor's believe that to protect patient's body. An antifreeze liquid is inserted in their veins. And gradually the body temperature is dropped. Normal Waters freezing point is 0°C whereas for antifreeze liquid it's -100°C. The benefit is that when the body's temperature is dropped the organs freeze before the antifreeze liquid. And a point comes when the body becomes solid as a rock. And at that point the body us put inside the liquid nitrogen tank. where it can remain preserved forever at -196°C. It takes doctors 12 hours to cryo protect the whole body. And for patients who have choosen just to preserved their head for them doctors perform six hour procedure. After cryo protecting the brain, it is also put inside the nitrogen tank. While passing through these steaming containers it feels like you're passing through a graveyard. It is very hard to believe that with the help of new technology they might be brought back to life again. Patients photos are attached outside every container and their family will be able to visit them regularly. We have seen the concept of cryonics in science fiction movies like Capt America and Stars Wars, But is the science fiction becoming reality or not?
