No, it's not silly to say such a thing. Just as aging minds are slower to recall (output), a defective brain (as with PD) may be slower to process incoming information (input).

But what needs to be pointed out about Fox reading so rapidly is what happens with advancing PD - I call it a "Sinemet high." I can be totally still (I am not tremor-dominate), and have to speak before a group or get the least bit excited about something and that's when the high comes on. Mixing replacement dopamine (Sinemet aka carbidopa/levodopa) with adrenaline and there is an excitatory response. Dyskinesia usually starts and my mouth rattles on - often with nonsense babble. I would guess that is what happens when Fox reads his book for recording.

You know, that is a really cool thing to do, however, read your own publication. And it also helps PWP who have trouble holding a book or turning the pages.
