The queen is a crazy old bat.
Actually, she is not. She is an amazing modern monarch and if anyone is crazy as a bat, it's her son and heir. It's no wonder she has retained her position even at her advanced age rather than let Charles and Camilla take over. At 92, she is still carrying out numerous public engagements for ceremonial and charitable events nearly every day (sometimes several a day), meets with the Prime Minister weekly, reviews a box of documents from Parliament daily, and supervises palace staff for Buckinghom Palace and Windsor Castle, especially for state events such as the reception of foreign dignitaries. Most people would have been dead two decades ago.
