Yeah, it is amazing how the brain processes stuff.
don't feel bad though, every time I see the word Gain, I pronounce 'John' in my head LOL!!
There is a mind game out there, where they write a paragraph, but scramble all the letters in the words. Even though they do this, like 2/3 of the people can still read it!
What it proves, is that we don't need the order of the letters to be correct, just so long as they are all there.
