Don't forget that it's also been processed to such an extent that it no longer resembles anything remotely close to its original base ingredients, and likely has the nutritional value of a piece of cardboard. Plant-based cardboard, of course.
This has literally been done for decades...the first version was done on September 2, 1952 when two University of Minnesota surgeons, Dr. Walton Lillehei and Dr. John Lewis, attempted the first open heart surgery on a five-year-old girl who had been born with a hole in her heart. She was Anaesthetized to stop her shivering as she was cooled by a special blanket until her body temperature reached 81 degrees F. At this temperature, she could survive without a pumping heart for 10 minutes, not four. Clamping the inflow to her heart so that it emptied of blood, Lillehei and Lewis cut open her heart, which was still slowly beating, and quickly sewed up the hole. With the repaired heart working properly for the first time in her life, the girl was then immersed in a bath of warm water to bring her body temperature back to normal. The operation was a success. It should also be noted that doctors have found that resuscitation is possible for cold-water drowning victims, particularly successfully for children, if accomplished within a two-hour window of the drowning, which has led to even further advancements in the technique of operating on a patient placed in hypothermia.
It really isn't practical...Mercury, orbitally, is the closest planet to the sun, but has no atmosphere so its temps vary greatly- from -279 to 800 Fahrenheit. That's hot enough to melt aluminum, and cold enough to freeze the ears off a gondark.
