Total lack of foresight there Charles....

foresight would have been needed, I installed the cable 40 years ago!

It's dreadful isn't it, Charles? I spent twenty years vaguely wondering
how the outdoor floodlamp that I fitted ten years before operated,
because it never came on. The other day whilst searching for something
else in the loft I found a scribbled circuit diagram. It turned out that
I'd wired the lamp to a switch that I'd forgotten existed because it had
been behind a shelf unit for the twenty years. I must have intened to
move the switch but never did.

Also, my oldest CCTV camera failed last year. It had worked 24/7 since
approx 1980. Unlike all the other cameras it was mains powered and I had
to physically follow the cable to find out where to disconnect it.
