I had one aged 83. It was annoying as hell, as playing English I had managed to get myself excommunicated at age 63 and thought "Oh well, it's not so bad - my king will die soon". After crusades from France and Germany, then war from Spain, I realised my mistake. Weird thing was, when the same king was fighting back several years later against France I got an excommunication warning, indicating that, to my surprise, I was no longer excommunicated. I can only surmise that the Pope died before my venerable leader!
