A scene from the film The Abyss keeps coming to my mind recently. Scientists have developed a substance that fills the lungs and enables the body to withstand the crushing pressure of the deep sea. To prove the substance's validity a pet rat is held under the surface of the gel much to the dismay of the rat's owner. The rat freaks out believing it is being drowned before realizing it can actually breathe this new alien substance. The human subject who undergoes the process also has the same unpleasant reaction. That moment of displaying the desperate survival instinct is what initially shocked me when I had first watched it years ago. Realizing that in order to exist in a crushing new environment one must first survive a little death.
In other words, transitions are hard. I'm more afraid now of how long it takes to acclimate to breathing a new kind of air than the little death that comes before but there is no choice sometimes but to just try and keep breathing.
A little obtuse, I know, but it's all I got for right now. Happy New Year.
