The Ticking Clock

Do you remember the building of the Berlin Wall?  Do you even remember the destruction of the Berlin Wall?  If you remember both, don't forget to keep doing your mental exercises so you can continue to do so.  If you remember only the latter, there's a good chance that the phrase that heads this blogentry is a metaphor for the passage of time, and nothing more.

Huh?  Of course that's what it is.  The biological clock is ticking, the clock is ticking on this project, the deadline, global warming...

But somewhen, bracketed by the rise and fall of the Berlin Wall, the non-metaphorical clock stopped ticking.  Now our clocks are digital.  If they look analog, they probably have quartz oscillators driving chip dividers running a liquid crystal display through a display formatter so you can see the mock hands "turning."  Cheaper than a spring, gears, and a hand or three.

Even as I "type" this our metaphors are outliving us.
