You nearly have a panic attack as you realize that you will rapidly come to your rather untimely demise. Clutching at your throat, you hold your breath for as long as you possibly can. Five minutes pass in deathly silence as you wait for the inevitable to happen.
You remove your hands from your throat as you slowly come to the realization that you are not yet dead. Holding your breath seems unusually comfortable and natural. In fact, what exactly is not holding your breath like? You try not holding your breath for a while. The task proves to be insurmountably difficult, as you have discovered that technically, you have been holding nothing at all. You have no breath.
You casually wonder whether this lack of breath makes you something of a two-dimensional character.
