Some twenty years ago, or so, I decided I wanted a tropical fish tank as that would be good feng shui. That was when I learned tap water kills tropical fish. It made me wonder if I should be drinking water that kills fish. The answer is no. And I don't want to bathe in it either. So I started treating my bath water with the stuff that takes chloramine out of the drinking water so the fish can live in it. And that's why I prefer taking a bath to showers. It's a bit expensive to treat bath water, but less than the cost of my life.
