If you actually counted the number of times a day we use a bathroom, especially if we have some intestinal problems, we probably would not realize how much time we spend in the bathroom, it occupies alot of our time. I know i like to know where the bathroom whereever i go. Just in case of an "accident". I also grew up with scarlet fever that affected one of my kidneys and i have scar tissue on it as was seen electronically. Could it be you need to know where the bathrooms are to get to them if an emergency came up?
