Dyslexic in English but not in Chinese
bmsleight writes "Research published in Nature and other sources has found that there is no one cause for dyslexia; rather, the causes vary between languages. The finding explains why one can be dyslexic in one language but not another language. Wow, time for me to learn Chinese."
Another thing that makes English difficult as a written language is that English has a very large number of vowel sounds, but all are represented by just five letters.
