> The amount of water that I used in Berlin to brush my teeth is probably enough for a whole day in my van. Maybe 80% of the water just flowed from the tap right into the drain without even touching my body.
I hear things like that time and time again, and I can literally not understand it. Why would any sane person leave the water running while brushing their teeth? When I brush my teeth, the water runs for one second to wet the brush, then for another second to draw water into a glass for rising my mouth with, then for another five seconds (on a low setting) to clean the brush. That's maybe 100 ml. I literally drink 15-20 times as much per day.
