My aunt forwarded me an email at one point.
Not sure where it is any longer.

It was a letter written entirely like that.
Except instead of a few lines, it was a doctor in some Californian university who had a thesis on word recognition in the brain.
And the letter was a full screen in length.

Like your above post, you could read the whole thing at only slightly slower then a normal reading pace.
If the first and last letters are correct, and the word has the proper number of letters, the brain picks it up very easily.
