You're in good company with Thoreau, Kant, Aristotle who all were famous walkers. I think the very speed needed for all the information processing would argue against the extra processing needed for awareness of function, active decision making, pondering, reflection. It is incredible to think about the complexity and speed of what's going on. I'm taking the Drugs and the Brain course on coursera.org for the 2nd time. It's been my favorite cousera course. One of the interesting tidbits in that course is that an infant is creating a million synapses per second up til about age 2. A very fundamental function from the recommended textbook is exocytosis. Vesicles in neurons move to the presynaptic terminal and dump their neurotransmitters into the synapse. So with all the speed of the electrochemical activity, here's a mechanical activity that's just as fast.
