Maybe a Heckler, word counts good

As time passes and I inevitably age, It’s impossible to completely purge from my thoughts contemplations of senility. I’m forever monitoring little forgetfulness’s such as children’s names, why I’m standing here in the doorway of this room having just switched on the light, or why have I rubbed that dollop of facial scrub into my still dry hair.
Little social indiscretions such as; wishing the video store girl good night at mid day, finding that I’ve walked all the way to the video store and back with my fly undone, or Trying to put the pie I’ve just purchased into my wallet with the change in my mouth, don’t worry me too much. I’m sure many people make them some much younger than I.
The thing is, I’m told, with this affliction it’s the short term memories like how do I get home from the video shop that go, whilst long term memories like all the lyrics to On Top of Old Smokey stay. Thus it is that I’m constantly cataloguing memory lapses / indiscretions into long term / short term categories.
Now I’ve never remembered names so that whilst forgetting the name of someone I’ve just met seems like short term category, I’ve always forgot them and that’s long term. Same goes for faces really, I’ve never been good at remembering them, come to think of it, my forgetfulness of faces has always compounded my forgetfulness of names.
The real problem comes with those crossover items of memory that are both long and short term such as which tap in the shower is hot and which is cold. These taps are clearly marked but not boldly enough for my failing sight. They also conform to a national if not universal standard, hot on the left, cold on the right. I know that now because I have my glasses on. I’ve also known it forever in my subconscious. Over all these sight filled years I didn’t need to look for red or green symbols, my hand did its own thinking and always got it right. Surely this is long term memory but wait, I turned them on yesterday and the day before, in fact every day and surely this is short term memory. Has then my short term dementia addled memory forgotten and taken hostage with it the long term memory.
If it is so is quite terrifying. Imagine if I were to find that dementia had deprived me of the memory of how to start the car say. I stated it only yesterday and as short term memory it is subject to dementia’s wiles even though I’ve started the car the same way for the last forty odd years (no not the same car) surely a long term memory just like the taps. Oh I hear you, obviously it is better to forget how to start it rather than forget how to drive it mid flight which must under these conditions also be regarded as a possibility.
