Mind power spelling

I've spent twenty years as as a teacher and have always found our brain and mind so fascinating. I've always felt people made way too big a deal about spelling. I've always been a pretty good speller so maybe that's why I can read the passage below so easily. I'd be very interested to see if "poor" spellers can read it as well...
