More twisting to fit. Your brain might be alive but without conscious. That is the point IMO.
No twisting. This witness just said that there would be oxygen to the brain and possible movement for at least 10-15 seconds due to oxygen reserves in the brain, possibly quite a bit longer. He also gave an example of someone who took a shot that shredded his heart and ran 65-75 feet before collapsing. It's quite possible according to this witness.
