I can think backwards; or was that 'He is backward?' :mrgreen:
I can read and write in 'mirror writing', backwards and upside down. All remnants of a service career, where you needed to read what your oppo had written on the other side of the radar-plot screen! Also, learned to read across the CO's desk, so I could see what he'd written about me!
I still have a habit of slipping into 'gnalskcab' from when I worked for a spell near the 'tekram-taem'.
