Twisted letters

Every now and then we see in newspapers or on webpages twisted letters. Sometimes arise funny words that are guaranteed not intended in this context. Somewhere I stumbled upon the following text, which drives it to the extreme.
 
Anricdocg to the sduty by an Egsinlh usevitniry, it deos not metatr in waht oredr the lteetrs in a wrod, the olny tinhg that is ipnartomt is taht the fsrit and the lsat lteetr in the crecort pitosion. The rset can be a taotl nenonsse, but you can raed it wohutit any plebroms. Tihs is baseuce we do not raed ecah lteetr ivlulidiadny, but the wrod as a wlohe.
 
Who could not read the lines above, for those here follows the answer to the riddle.
 
According to the study by an English university, it does not matter in what order the letters in a word, the only thing that is important is that the first and the last letter in the correct position. The rest can be a total nonsense, but you can read it without any problems. This is because we do not read each letter individually, but the word as a whole.
