Should Elizabeth II — by the grace of God, of the United Kingdom and Northern Ireland and of her other realms and territories, queen — resign?

The Emperor of Japan has said he'd like to. He's 82 and is "beginning to feel his age." She's 90. And as far as the hawk-like attention paid by the royal correspondents has recorded, the queen has been as impeccable as ever. If with a reduced schedule. But 90!

Her heir, His Royal Highness Charles, Prince of Wales, Duke of Cornwall, Earl of Chester, Duke of Rothesay, Earl of Carrick, Baron of Renfrew, Lord of the Isles, Prince and Grand Steward of Scotland, is pushing 70. His elder son, His Royal Highness Prince William, Duke of Cambridge, Earl of Strathearn, Baron of Carrickfergus, Royal Knight Companion of the Most Ancient and Most Noble Order of the Garter, Knight of the Most Ancient and Most Noble Order of the Thistle, Personal Aide-de-Camp of Her Majesty the Queen, is 34. The designation "early middle age" is heard more often than "young."
