2. It’ll save a lot of waterBack in 2014, students at the University of East Anglia in Norwich calculated they could save a pretty large amount of water if all their colleagues peed in the shower once a day. By large, I mean “enough water to fill an Olympic-sized swimming pool 26 times” annually. In other words, the university would conserve the equivalent of one Olympic-sized pool every two weeks. In fact, flushing the toilet accounts for between a quarter and a third of all the water you consume over the course of your life. So save water, and pee in the shower.
