The copper wire might not but the insulation around it certainly does -
especially if there is some ozone about.

What ozone source are you referring to?

Take a look at what happens to
Post Office rubber bands after a year or so and then worry about it!

That might apply to flex, but my house wiring (twin and earth etc) doesn't seem to go the same way.

If you are still on prehistoric round pin plugs and wire fuses then it
is probably time for a rewiring by now.

Nope, 1979 wiring. Wire fuses and square 13A sockets. I prefer wire fuses as they aren't over-sensitive. The only circuit beakers I got (plug in type in place of the consumer unit fuses) was for the lighting circuits, as a blown halogen bulb could damage a PIR sensor before the fuse blew.

There is also the risk of rodents sharpening their teeth on your wiring
with accumulating damage until they bridge live and neutral. But that
can happen to modern wiring sometimes if you are very unlucky.

I've had rodents in the house a few times, but they've never gone for wires, only things like cushions and poly bags. If they did it should blow a fuse, or the rat.
