I make it a practice these days to walk regularly. Not merely to get from the couch to the refrigerator, but rather outdoors, and for the purpose of keeping physically fit. I used to run, but years ago I one day committed the grievous error of not lifting with my knees, but with my back instead, and have lived with chronic back pain ever since. It's not so painful as to incapacitate me, but it never lets me forget that it's there. I've found that if I walk briskly for three or four miles, the aggravating affliction disappears- but that's not the point I'm trying to make, so please excuse the digression.
A few years back (yes, I've been at it for a while, now) I was out for my daily constitutional, when by chance I saw something that made my so-called mind flash to something relatively sick. (I know- hard to believe......please don't press me for details.) The offending thing happens to be a permanent feature which happens to be on my customary path, so I happened to resolve to never again think of it. So of course I see it and nothing but, and think about the disgusting image it provokes every single time I walk that way. I have tried closing my eyes when I approach it, but that proved to be a bad idea the day I wandered into the path of an irate bicyclist. Re-directing my focus sometimes works, but it has now got to the point that the unhealthy vision pops into my head if I so much as glimpse an image similar to the one I try to avoid.
I realize that we're all just human, and that we may all be subject to the occasional insane idea, but I take no solace in realizing that. It's a curious shortcoming- that ability to control our own minds. If I tell you not to think of the word "possum", you will inevitably not be able to think of anything but "possum". A whole n'other popular manifestation of this lack of forbearance is the inability to get out of your head a particular song or tune- usually an extremely annoying jingle from a stupid teevee commercial, or some song dating from the disco era, or by Barry Manilow, Pat Boone, or others of that ilk. I spent my whole afternoon walk recently trying to purge my mind of the tune "Staying Alive". Picture that one taking over one's consciousness while out striding purposefully.
I suppose the point of all this is to cut myself some slack. My cognitive functions, I realize, are sometimes beyond my control. As long as I don't act on the weirder ones, and do instead focus on the productive and/or creative ones, I'll be okay. And let's face it, sometimes the most debased ones lead to rewarding results. Why do you think it is that we eat oysters today? And speaking of possums.........(thanks to my cousin Clint for this one)........ (caption below for those like me)
