That’s so cool.
“I couldn’t believe that I could actually understand what I was reading. The phenomenal power of the human mind, according to a research at Cambridge University, it doesn’t matter in what order the letters in a word are, the only important thing is that the first and the last letter be in the right place. The rest can be a total mess and you can still read it without a problem. This is because the human mind does not read every letter by itself but the word as a whole. Amazing huh? yes and I always thought spelling was important! if you can read this forward it.”
I wonder whether this only applies to the native tongue or a language that the reader is fluent, because it would be so much harder to guess and recognise the words if you do not know/understand them.
