Apropos of nothing in particular, does anybody have any idea what the oldest continuously maintained system on Earth is?
I’m thinking Chinese canals, Roman waterworks or bridges, and so forth; but the answer could be some more social or political, I suppose. The hierarchy of Judaism, for example.
Heck, does anyone want to take a shot at refining the question?
