I know it's simple physics - is that an oxymoron? - but I can't help thinking there's more to it. As a non-scientific person whose brain does not easily travel to the land of 'matter and its motion and behaviour through space and time', I glibly accept that there are universal laws which govern such things. I take gravity for granted except when it works against me. When something that I don't want to move, doesn't move for a while, but then does move, I curse gravity which is really silly, but there you go.
I'm a reasonably logical person, but only to a point. At a certain level of relentless logic, I flounder. I just can't follow it. Sometimes, I even wonder why I need to comprehend such things.
So it is, that as I walk along the footpath, my gym bag works its way off my shoulder. Every so often I have to move the strap back to its start position: the one I think is comfortable and immutable. Of course, it stays for a while, right where I want it to...but inevitably it begins to move. The most obvious explanation has something to do with the slope of my shoulder, and the rocking, swaying movement of the bag as I walk. Nevertheless, I wonder.
I listen to music on my iPod shuffle as I walk. I have earphones with hooks to lock onto my ears because my ears are the wrong shape to hold earbuds. That's genetics, which incidentally is another thing about which I have a very rudimentary knowledge. The earphone cord moves as well. It sways like the bag, so that every so often it is no longer loose on my chest, but tight. Tight enough to tug the cord and cause discomfort to my ears. I have to keep moving it back to the start position, because it won't stay there. Dammit.
Even on the cross trainer, I am endangered by this progression towards the wrong place. (Does anyone have any idea where I'm going with this?) The earphone cord, now plugged into the cross trainer's console so I can enjoy The Chase as I awkwardly walk/run with my arms in an unnatural position, swings. Of course it does. It's physics. Every now and then, randomly or so it seems to the non scientific brain, it swings so high that my thumb which is wrapped around the handle of the cross trainer, snags it and jerks it upwards. I'm sure I don't need to say anything more about trauma to my ears.
My stunning conclusion? Everything in life moves into an awkward position. And with that ludicrous and unscientific generalization, I leave you.
