I doubt the accuracy of this assertion. The almost instantaneous loss of blood pressure is unlikely to allow conscious thoughts of any sort.
Yes, but is that all that is needed for it to work? The brain is just part of a system, and one which is severely damaged by decapitation. We know unconsciousness follows immediately on a severe blow to the head, and decapitation is far more direct damage to the system than that.
Mm. Perhaps, perhaps not.
"does this make me look fat?"
wont need to get that haircut..
The lack of blood flow to the brain would cause the loss of consciousnesses within in 3 seconds not 30. barely time to think ouch that stings.
An unconscious brain though alive has no thoughts. It's pretty easy to demonstrate just pinch off your carotid arteries in your neck and see how long it takes. you will generally loose consciousnesses within in 3 seconds death will occur perhaps as long as 30 seconds later. The loss of blood flow to the brain is why you get dizzy and pass out if you stand up too fast.
no it isn't
Depends on the head.
Mmmh. I'm feeling a bit top heavy
wtf? wtf? wtf? wtf? wtfwtfwtfwtfwtf??????
