put a early frustration to this.
put two hands together. now decide left right which way. NOTE how FAST reaction is and how there's nearly no indecision.
Now separate your hands apart some. keep deciding left/ right , left/right, or think gore point on the freeway, boy/girl, boy/girl. you goin south or north.
now separate those hands past the peripheral vision, and past the shaman "view of the hawk"
you can't decide to go left or right anymore because too much processing time in the decision.
the inbetween small space was best for decision, no wiggle room, no distractions, no extra fluff, no foreign material
