At this moment, I’ve been living in one of the poorest countries in the world for one year, three months, and two days. I can’t use the tap water to rinse my toothbrush, much less to drink. All of the water we use must go through a high-quality, Swiss-made ceramic filter. But that’s quite a luxury, really, since one of those filters costs half a year’s salary for the average worker here. Sometimes the water in our house shuts off for a few hours — or even for most of the day, and we have to flush the toilet with water reserved in a bucket alongside.
