^^^ That is really amazing.... I recall screening a programme some years ago where they conducted an experiment to see what could survive unaided in some sort of container left in some sort of cabin through the Winter. They did this at the north pole (I think?) where they did not think anything could survive the freezing Winter. They returned months later to check, and sure enough, whatever it was they left in the container was still alive. It is a bit creepy really..... (LOL)
