Depends (a) on the relationship (b) the wife's voice qualities (some gifted
talk show hosts have somehow such compelling voice qualities that you
would not find them reading the phone book out loud to be all that
boring) (c) just how good your own verbal memory is. Of course,
I'm probably taking your question too literally.

Few people would or should make that claim. But then, what you
are trying to explain is what the "nuances" really amount to.

You bet it's debatable, what with QM and the Bekenstein bound.

Now you've got my attention, and we may have just progressed
from SL2 to SL3 --- I hope Eliezer and the list snipers don't parse
for " SL* " :-)

At least. And though we are just discussing principle, there
are the other senses that should be given passing mention.

I'm missing what you are getting at with that question. Oh, on a
second re-reading, I get it. That is, for example, do I squint so
that the incoming bandwidth isn't any greater than the bandwidth
to my memory? (There's another sentence that could have been
restated and embroidered with "That is...", or "In other words..."
:-) But I'm just on a kick right now of trying to make other
people's emails more accessible to me (e.g. so that I have
to make fewer conjectures as I read, and it's easier to confirm
the ones I do make), so forgive the stylistic lecture.)

I can't remember ever doing that. That is, I don't recall ever
turning down the volume of an incoming podcast to grok more
of it (unless, naturally, it's so loud that it's *preventing* information
flow), or trying to skim written material IN ORDER TO notice
less of it----ah! Thanks! Yes I do. Often, especially with pages
I already read or which seem overly redundant I have found,
as per your prediction, that I can more accurately "remember
what I perceive".

But still, if I take your question above quite literally, the answer
still is no, I think. BTW, what has this to do with Memory
Merging Possible for Close Duplicates?
