If you are in a wheelchair and cannot stand up for any length of time, the "handicapped" toilets (anything taller than 18 inches) is a disaster waiting to happen. This is especially true if you cannot lift your own body weight. I had trouble with these "Mount Everest" things before PD and now they are impossible without help. They are designed for people who can walk but have a hard time rising from a seated position. Marvin Giles ----------
