So you're saying you can sit on a chair, left and right HOTAS, and you twist your body and look over your left shoulder, and your vision of focus reaches to 4 and 5 oc angles?
I assume that your not talking about a 'glimpse' in the peripheral vision, but a fully focused view where you can make out object detail clearly(as we can do so in AH 6views).
That's pretty amazing.
A typical human neck pivots about 90 degrees to left and right without any torso/spinal movement. A typical human spine has about 60 degrees spinal twist max(pure spinal), with additional 45 degrees coming out from the pelvis and hips, thus a "torso twist" is about 100 degrees maximum for a human.
If you can look over your left shoulder and see the 4 and 5 oc clearly, your torso twist is close to 140~150 degrees. Sitting on chair usually halves the twist angle in the hips, so it would mean your pure spinal twist is close to 100~120 degrees. A normal person would break his back if he does something like that.
You are indeed, one of a kind!
[edit] Some spinal facts:
The golfer Tiger Woods, twists his body about 100 degrees with his feet planted solid when in a backswing.
His hips twist about 30 degrees, and his spine twists about 70 degrees, which is remarkable flexibility. Normal amateuer golfers needs about 45 degrees of hip twist and 60 degrees of spinal twist to achieve that kind of swing. [/edit]
