Truly a case of the blind leading the blind.

Why does it need to be explained?  There are chess masters who
can play 20 or 30 games of chess all at the same time, without
looking at any of the chessboards.

You do something for a long time, you develop excellent memory
regarding that thing.

What's so strange about that?

You have memorized the key positions and the music.

Most blind people have some sight and can, in fact, see the
furniture.
The totally blind memorize the position of objects in the room.  Part
of the therapy provided to the newly blind is to train them in how to
memorize object locations and to always put things back.  It is also
possible for blind people to learn to "see" objects by listening to
reflected sound, much as a bat uses echo location to fly.

How about a regular non-doctor person?  

I had a discussion about this just recently.  When my brother learned to
play the piano, the teacher had a ruler.  If he looked at his hands, she
would whack him on the back of the hand with the ruler.  Her students
learned quickly not to look at their hands while playing.  She was more
forgiving with the beginning students.  If they looked at their hands,
despite her instructions not to, she would simply hold a piece of
cardboard between their eyes and their hands.

My father chimed in at this point.  When he learned how to type at
school, all of the keys were removed and replaced with blank keys.  It
did no good just to look at the keys, since they were blank.  The
students soon learned to "touch type", which is how nearly all
proficient typists work.

If you watch someone tie their shoes, they seldom keep watching once
they've gotten started.  The fingers just take over.  

This is true for many things in life.  For the workstation that a person
normally uses, it isn't necessary to look at the mouse.  It's right
where you left it.  Once somebody has had a sip of coffee from their
regular cup, and set the cup down on their usual table, they may not
need to look when getting a second sip.

Blind people memorize the furniture and layout in a room.  They can move
confidently after learning this information.  For an unfamiliar room,
they "probe" with their white cane to find out where things are.  You
will often see them circling around trying to find something.  I never
know what to do, since some of them resent help because they don't
really learn unless they do it themselves.

ObHintToSightedPeople:  Don't ever rearrange the furniture in a room
used by a blind person without telling them first.  If you like to
rearrange rooms frequently due to aesthetic reasons, think again.

Address your question to Zetsu. It was he who said that vision, memory and
imagination were all "correlated" and one could not be present without the
other. Zetsu promised us that blindness could be cured by fixing the
imagination and the memory.

I don't believe this is true, but you're free to argue with him about it all
you like. This newsgroup appears dedicated to idiotic arguments with no
basis in reality and no relationship whatsoever to established science.

As for you and Zetsu, I'm pretty sure you never met a blind man, much less
cured one.
