I did not know about these details regarding the hibernation of turtles. It is an amazing feat. Six months without moving, without breathing, literally dissolving part of its bones and shell to use the calcium in order to neutralize the acidity in its muscles including its heart. The acidity caused by its voluntary immobility. A reflex that is instinctively triggered by an internal warning in its brain for the imminent coming of a freezing winter. What a wonder of nature! The power of simplicity and stillness. The turtles could withstand the freezing temperatures of the harsh deadly winter and avoid death, through stillness and quietude.
