The process of Cryonics, it’s a technique used to store a persons body at an extremely low temperature with the hope of one day reviving them. You may of seen this method used in many sci fi films for example the demolition man, But, the science behind this process isn’t just fictional, it actually does exist, and the technique is being performed today. However it is still in its very early infancy. The idea of being cryogenically suspended is that if you die from a disease or condition that is currently incurable, scientists freeze you. Then one day in the near or far future, when the technology has been created to revive your body and the cure for the disease or condition has been discovered, you will be brought back, cured and allowed to carry on your life, only in the future. So how does it work? Well first you would have to join a cryonics facility and pay an annual membership fee. Then, when you are confined legally dead, an emergency response team from the facility stabilises your body, supplying your brain with enough oxygen and blood to preserve minimal function until you can be transported to the suspension facility. You are then packed in ice and injected with an anticoagulant ready to be transported, once you are at the cryonics facilities the team remove the water from your cells and replace it with a type anti freeze called a cryoprotectant to prevent cells from freezing and shattering. Your body is then cooled on a bed of dry ice until it reaches -130 C and then you are inserted in to an individual container that is then placed into a large metal tank filled with liquid nitrogen at a temperature of around -196 degrees Celsius. This isn’t a cheap process however, currently it costs more than 100,000 to have your whole body preserved. The kind of price that Walt Disney would of been able to pay all those years ago. However the fact that everybody thinks they know about the famous Mr Disney being preserved though cryogenics after deaf, is actually incorrect. It is only an urban legend, Walt was cremated in 1966 after he passed away. In actual fact, James Bedford became the 1st human to be cryogenically preserved on 12 January 1967. Currently there is around 150 people that have had their whole body stored in liquid nitrogen in the United States, while around 80 have had just their heads or brains preserved. So does it actually work? Will science ever bring back James Bedford? Well, currently none of companies offering cryogenic suspension have successfully revived anyone, and dont expect to be able to anytime soon. One of the biggest problems with this process seems to be that if the scientists do not warm the body at exactly the right speed and temperature, the cells could form ice crystals and shatter. However there are studies in to some frogs that have a natural antifreeze in there cells which can protect them if theyre frozen completely solid. This may one day be adapted to the human body, potentially solving this problem. Another method that may be available in the future, is nanotechnology. These tiny little bots may make it possible to repair or build human cells and tissue if it becomes damaged during the cryogenic process. This may sound like a Sci Fi story as seen in many films, but some scientists have predicted that the first cryonic revival might occur as early as the year 2045 and there are more than 1,000 living people who have instructed companies to preserve their bodies after their death, on the hope that these scientists one day, will bring them back.
