Hi,
I will watch your YouTube channel. I am curious to learn about EFT. By the way, I have seen the toilets you are describing, but not in Brazil. I think it's a great idea. In Japan, we typically us "wash-let" which are basically high-tech butt washers, but I find the water flow of wash-lets to be too weak for my condition. Basically, I never feel complete after I go to the toilet, and every day I need to clean the inside of my anus with water. My question is this: the hose that is by the side of your Brazilian toilet, how does it stay sanitary? Must the user wipe it clean before and after use? As I said, I have seen these hoses on other toilets but never tried them because I was not sure they were clean enough to use, and I didn't want to get an infection.
