The correct text IS :
I couldn't believe that i could actually understand wat i was reading. The phenomenal power of the human mind, according to a research at cambridge university, it doesnt matter in what order the letters in a word are, the only important thing is that the first & 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 doesn't read every letter by its self but the word as a whole. Amazing, huh? yeah and i always thought spelling was important.
and for who can't understand all this ....
