My own personal instinct has the week starting on Monday, so that’s how I set up all my devices, but my partner feels like it starts on Sunday (and likes to tease me some Saturdays by going, “next week…” when what he really means is, “tomorrow…").

Wiki: Aral Sea

The Aral Sea was a large salt-water lake, straddling the modern countries of Kazakhstan and Uzbekistan. It was fed predominantly by two rivers - the Syr Darya in the north, flowing through Kyrgyzstan, Uzbekistan and Kazakhstan, and the Amu Darya in the south, flowing through Tajikistan, Afghanistan and Uzbekistan. In 1960, it was the fourth-largest lake in the world, but the Soviet Union had a …
