Jock, vision is my excuse! You should see me struggle repleating a black watch 6 decades is real close here.
My biggest typo source is "floaty hands" on the keyboard. Learned to type on the old manual machines and lost the homekeys positioning habit when we started touch typing. I proof read and still miss things. English is a living (changing) language that seems very dependent on the local culture for context. Am still butchering the termonology used with kilts and the sister lingo used for pleated skirts. Entertaining at times.
