We don't like to speculate on someone's future death, especially someone who isn't even sick, but Queen Elizabeth II is 91 years old. The British monarchy is mostly ceremonial these days, yet Elizabeth's subjects take it very seriously -or at least the ones in the UK do. There is a set procedure in place to handle getting out the news when the time comes, to be followed by a funeral and the coronation of Prince Charles.
A monarch's death sets up a whole slew of changes we hadn't thought of, like reprinting all the money to reflect a new monarch's face. What? American cash, for all its drawbacks, never goes out of style because everyone on the bills is already dead. -via Mental Floss
