Omg I’ve asked the same questions. I can’t squat because of my knee problems. I just get down as far as I can and hope for the best. Then if there’s a hose, I hose all the bits that missed. My daughter says 80 year old women can use them. Why can’t you? My answer. They are taught to use them from a very young age and their knees have developed more flexibility than mine. In Japan once I used the hand admin to help me up and the bloody thing came clean off the wall. I have so many toilet stories to tell. The safest thing for me is to look for a disabled toilet. They are western style and even have handrails. 😳
