Without prediction, we wouldn’t be able to _walk_!

  There is a lot built into the biomechanics of your legs too. The relevant term is “passive dynamics”.

    And a lot of unconscious thought for the biomechanics of the body. https://radiolab.org/episodes/91524-where-am-i https://radiolab.org/episodes/91524-where-am-i The section on Ian Waterman. Another article about him - https://mcneilllab.uchicago.edu/pdfs/IW_lost_body.pdf https://mcneilllab.uchicago.edu/pdfs/IW_lost_body.pdf > Mr. Ian Waterman, sometimes referred to as ‘IW’, suffered at age 19 a sudden, total deafferentation of his body from the neck down—the near total loss of all the touch, proprioception, and limb spatial position senses that tell you, without looking, where your body is and what it is doing. The loss followed a never-diagnosed fever that is believed to have set off an auto-immune reaction. The immediate behavioral effect was immobility, even though IW’s motor system was unaffected and there was no paralysis. The problem was not lack of movement per se but lack of control. https://topdocumentaryfilms.com/the-man-who-lost-his-body/ https://topdocumentaryfilms.com/the-man-who-lost-his-body/
