I remember doing some experiments in psychology class many years ago with visual illusions like the top hat illusion. We could teach our brains to ignore some eventually. I’ve never fully trusted my sight, hearing or any of my senses since. I found it very interesting but I was out of my depth...
I thought i would stay 2-3 too, but it is nearly 23 years. The apartments are usually small and the outlets mostly have 2 prongs or receptacles(?) instead of 3. It is easy to get adapters here and even step up/down transformers if you need them.
