I debated on what it would be like before I posted and I think you're right. It would be more like being "in the mirror" sort of. Everyone would look different to you and you'd look different from what people remember. You'd need to learn to read and write in reverse.

Well in that case you starve a slow death of malnutrition as your body is unable to properly process any of the food you eat, unless it's also rotated 180 degrees along the 4th axis
