A woman just told me she had her house rewired because it hadn't been

just leave it? Wire doesn't rot.

The copper wire might not but the insulation around it certainly does -
especially if there is some ozone about. Take a look at what happens to
Post Office rubber bands after a year or so and then worry about it!

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

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.
