The report that blinking gives your brain a break by taking pauses while reading reminds me of the views of Hollywood film editor Walter Murch in his 1992 book In the Blink of an Eye (11 January, p 17).
He says the difference between a good actor and a bad one is in the timing of a blink. A good actor will blink at the point where their character understands what has been said, usually coinciding with the end of a sentence, whereas a poor actor will blink randomly.
