Quite clearly true TB

From the antique radio and light at her breakfast table, to the unaltered state of her rooms, to the running of her household.... Her Majesty is obviously no fan of change.
Which will make it all that much more interesting to see what happens after the present reign ends. If The Queen lives to the same age as her mother, she will have reigned for some 75 odd years at her death, and over 80% of her subjects will have been born during her reign. Given three quarters of a century of consistency, even minor changes made by Charles (or William) will seem enormous by comparison!
Example: Let's say the next King decides to adopt the practice of the monarchs of Scandinavia, Spain and Belgium, who all live in a suburban residence, while the main capital city royal palace is used only for receptions and court functions. Perhaps we'd then have the King living at Windsor Castle and coming to BP only for investitures, receptions and audiences?
To most people that might seem unheard of - but then, prior to 1901 the monarch spent much of the year outside London anyway.
