[1]384-cr2oi6Groceries and theoretical physics Amazed at the
  human body: Everyday stuff that's practically theoretical
  physics complex: I collecting groceries to bring to the house.
  Three large bottles of water with handles, opening up a bag and
  putting loose items in, opening up the bag, and putting things
  in while holding the bottles, configuring and reconfiguring the
  positions of my fingers clasped around the handles of each,
  shifting them around from one side to the other until I got the
  perfect configuration where I could shut the door with a loose
  elbow...
  ...and I thought to myself as I'm doing it, "How many
  calculations would it take to figure out that *this* is one of
  the optimum configurations of my fingers, hands, twists, elbows,
  shoulders, in relation to my body in relation to each of the
  items I'm carrying, and the steps I did to get there? What I did
  was everyday. We all do it. Yet think how mathematically amazing
  it is if we tried to get the formula to calculate all of that. I
  don't think our brains do all of those calculations though.
  There's a concept called Affordances, which makes a little more
  sense to me. It's hard to grasp at first, but basically "things
  find themselves in the optimum configuration at any given moment
  given the circumstances they find themselves in". In short, they
  do what they're able given the situation and changing as it the
  situation changes. Everyday theoretical physics level math. ==
  Oh yes there's definitely a kind of muscle memory, but consider
  the relationship between the organism, its capabilities, its
  task and the environment. That's what affordances touches on. It
  goes beyond the organism and its neural activity and enters into
  a mindset where we might think of robotics that are using
  minimal computations to accomplish tasks. == Well, I think
  that's part of it, but I think there might be a little more to
  it in the case of optimum fitting situations. The ability to
  gauge size and "fittingness" is something we can do in our
  brains without physical objects present. Granted, it's something
  we have trouble with when we're young - and some people never
  overcome it. [the famous experiment of gauging liquid volume is
  an example some people have trouble overcoming]
  [2]https://www.researchgate.net/.../Figure-1-Two... Yet, one of
  the things that IQ tests famously measure is the ability to
  rotate objects in 3D in the brain. Gauging how to move a couch
  through a doorway for example: Some people can "see" how to
  rotate it just right so that it will fit, without even having
  had any experience moving. Other people will forever break the
  frames around doors because they can never see it. And inbetween
  the two extremes, some people learn through experience. So I
  think likewise with using fingers/hands/wrists/elbows/shoulders
  along with loose groceries, putting in bags, putting the hatch
  of the car down. Much of it can be attributed to learned skill
  of course. At the same time, when did we learn it? When we're
  toddlers we carry our toys to and fro. We drop things. We pick
  them up. We want to bring EVERYTHING with us at that age. Maybe
  the learning primarily takes place at that point. That would be
  the period of time that gets obscured by the age of 7 or 8, so
  that the same memories of when they were 3 yrs old that are
  available to an average 6 year old, are no longer available to
  the average 9 year old. Amazing how in 2-3 years that there's
  such a strong "forgetting curve", although it's not really
  forgetting, but "incorporating". The event specifics may be
  fuzzy or difficult to recall, but the memories have been encoded
  in our emotional responses, our "automatic" muscle memories and
  such. So, I think you're right and at the same time, I think a
  lot of the encoding takes place extremely early. == Quite true.
  I'm not knocking the ability of grown adults to learn new
  skills: brain has tremendous plasticity. I've always had
  coordination issues from when I was young: they had special
  training for me when I was in that critical 1-4 yr old range to
  overcome most of it so that I was able to enter regular school
  without anything noticeable. But I think consequently, I'm extra
  "conscious" of the positionings of my body. I can sit here and I
  know what my 3rd toe on my right foot feels like at the same
  time as my left eyebrow and the state of my intestines and how
  my eyelashes are touching my glasses while typing and thinking
  my thoughts and hearing a song playing in my head. Nothing
  special about these things, but having a hyper-awareness of
  muscle position and nerves at every given moment of any day I
  think makes me appreciate the tremendous burden on babies and
  toddlers in learning how to use their bodies properly. My
  process had to be helped along, right into the 3.5/4 yr old
  range, when the first adult-recallable memories will stay behind
  firmly. [I have some from before that age but they're more like
  dreams]. It takes a lot to ignore all the "input" from
  everywhere and it's kind of annoying at times but I'm grateful
  overall. == Please do: I enjoy this kind of stuff smile emoticon
  I'm unfortunately excessively self-aware of my programming as it
  operates: the subroutine that monitors an overview of functions
  as they are happening is always displayed in the corner of my
  conscious thought. So, while programmed, the status monitor is
  the thing I have to ignore a lot: the control panel to modify
  the automated systems is RIGHT THERE within reach and so, I
  often mess with it in real time, sometimes to my detriment. For
  example, while speaking. I'm conscious of speaking as I'm
  speaking, conscious of muscle movements of my vocal chords,
  positioning of tongue, so much so that I barely can think *what*
  want to say, as my consciousness is wrapped up in the process of
  speaking itself, trying to get everything right. I envy those
  for whom these processes can be ignored and allowed to operated
  "automatically" tongue emoticon Had a stutter when I was little.
  3rd grade, speech therapy. Learned how to consciously control
  mouth, tongue, throat, pause, think about positioning. It worked
  great to fix the stutter. Created a little "pause" in my
  consciousness, like an extra processing node of self-monitoring.
  So, I suspect that little 'nugget' of extra processing space
  remains. Closest thing I can figure. == Weird example: As I
  walk, there's something akin to "this guy" in my head. I'm aware
  of "me" as I'm moving, intentioning and all of that. But then
  there's _this_ dude (something like that), which shows my center
  of gravity, the placement of my feet, the pressure I'm pushing
  down, the positioning of arms and hands. Head positioning I have
  less of an awareness of but the rest is always there. Kind of
  annoying because it's hard to ignore sometimes. Center of
  gravity is like a nugget or floating ball in my middle somewhere
  that floats around and moves and my body kinda works around it.
  [and your post just showed up so I'll address that - here tongue
  emoticon ] Well, you mention "where did these people get
  programmed?" and that's the part where my way of thinking
  diverges: I'm _too_ aware of programming attempts on me through
  the years, where my biases come from, although I discover
  forgotten ones all of the time, as I'm always on the search. So,
  it's hard for me to see "other people" as running _fully_ on
  automatic, but I can see when someone has acquired some habits
  that can easily vanish when they're pointed out. == Oh I've
  encountered the way of thought your talking about. I mean,
  people _do_ run on automatic. But de-automating isn't difficult.
  It's not de-programming to me, as I don't care to change
  someone's political views. They have their reasons, some
  rational and some irrational just as anybody and everybody has
  rational and irrational bits. But you can tell if you've made
  their automated process manual again if they speak to you as a
  person. Even for a moment, if they can see you as a fellow human
  being (and you can tell by tone, choice of words and such, and
  that can be conveyed via text as well as any other means of
  communication), then you can see their self-awareness of their
  OWN processes and an awareness of yours. To me, if I can reach
  that point even for a moment, I know I'm not taking to an
  automaton but to a human and that is one of my strongest biases
  of all: that we really ARE all human individuals and I make it a
  quest to find "that human" within the automated responses. How
  they behave when I'm NOT around? That's their business smile
