 You know, my sister-in-law told me she has cataracts. My first thought, she lives in rural Virginia, and I know the water is really, really hard. And I thought that's probably, you know, the course of, you know, hard water over a period of time. Kidney stones. You know, kidney stones and gallstones can be a cause of hard water. I know kidney stones can also be affected, you know, by, you know, poor diet. But, boy, you drink plenty of water and you have RO water. Sure. It's a flushing agent. I drink a lot of water, the ice cubes.
