Once in a while you hear something you never heard or thought of before. This was one such time, and I cherish those moments that seem to become rarer and rarer. It is not that I know everything, but on a shallow level I have heard about a lot. This especially goes for history. When I was young, I did not have much continuity in my understanding of history. I knew some events here and there, but mostly there were voids in my knowledge. Over time, I have filled in many of the voids. Not to some deep level, but to a level that when someone mentions something in common contexts, I have usually heard about it before. It is always possible to go deeper, but I would like it better to learn more breadth-first so to say.
