Document Summary
Such that we can turn our heads while running without having to turn our body: light heads, scapula are positioned on the back, arms extend right out to the side with the perfect arm length so that the swing of the arms while running it counter balanced leg movement, springy vertebral column for energy conservation, large investments in gluteal muscles for powerful leg extension, neck of the femur is close the centre of mass and bow inwards for a vagal knee, large contact surface on the knees to support large forces, ankle is super stabilized, big toe is reduced and retracted to make a slipper like foot, arched foot with calcaneal tuber so that every time we step we can return energy, sophisticated brain cooling system in our nose with counter current heat transfer so that our brain doesn"t liquefy while we run.
