And I know more than myself, either a stutter or a stammer. Out of the 50 supervisors at my work, 10 of them have the condition. Of the hundreds of other workers, I've met others that come through...at least 5. We all have personal anecdotes. Also, a great example of the density...there are entire companies focused on employing the blind. That means it is likely for blind people to more often interact for other blind people, even if some of them don't see it.
