When an article says "some scientists think" then remember this: I, a scientist, once thought I could fit a whole orange in my mouth. I could, it turns out, get it in there, but I hadn't given sufficient thought to the reverse operation.
I should also, on reflection, have practiced in private. I had an audience, which grew as my initial satisfaction at an hypothesis well proven, slipped rapidly through stages of qualm, disquiet, then alarm (mild through severe) and ended in full blown panic.
When one panics, one's muscles tense, which is of course, the opposite of what I needed here. I had been quite relaxed at the start, but now I couldn't get a finger between the orange and the very taut edges of my mouth.
Above and below, the orange, which was now under some pressure, deformed to make a nearly perfect seal against my teeth. I hadn't previously been aware of how much oxygen one needs to consume an orange, but I was made aware of it now by its sudden and ongoing lack.
I forgot for a moment that I had nostrils and tried to breathe in hard through my mouth. I have big lungs. When the doctor tested my lung capacity, I blew the end clean off the cardboard tube.
I've always been vaguely proud of that; mostly for want of more tangible achievements and because I am, when all is said and done, the kind of person otherwise predisposed to shove a whole orange in his mouth without cause.
Those enormous lungs - my pride and joy - expanding in this moment of crisis to their fullest extent, had created a hard vacuum behind the orange, which, at that point imploded.
From now on, things which had been unfolding at an almost leisurely pace, started to happen rather fast. So, I will take this opportunity to say that no one had actually tried to help me up till now. This was not for lack of opportunity.
Later, someone mentioned the kind of details - veins like worms scribbling incomprehensible messages across my forehead, eyes popping out as if on stalks, laced with tiny red veins - which one can only truly apprehend at a distance that wouldn't have made help impossible.
