Today's show explains why a significant number of France's high schools were closed Tuesday and provides different perspectives on the ongoing protests. We're also looking at the costs of Halloween goodies and why some food manufacturers have changed labels from saying "milk chocolate" to ones that say "chocolate candy." We explore historic topics related to the Israeli-Palestinian conflict and America's longest war. Plus: the way of the Samurai, the Silk Road settlement under an Asian lake, and the disposal of robots in molten steel.
