I wonder how long you'd remain conscious after slicing thru the carotid artery going up the left side of your neck, supplying your brain with blood? I mean, since the blood pressure going to your brain drops to 0, the edges of your vision should quickly darken, the darkness tightening until you can no longer see bc you're no longer conscious. It should be pretty quick, then you'd just bleed out, never waking up. Maybe 3 seconds of discomfort before it all goes numb and disappears? Maybe 5 seconds? It should be over pretty quick is my suspicion anyways..

To clarify the medical reality, the process is far less "neat" or "quick" than your suspicion suggests. The human body has significant biological redundancies designed specifically to prevent the brain from losing consciousness during trauma.
The Reality of Cerebrovascular Anatomy
The brain is not supplied by a single pipe. It is supported by the Circle of Willis, a circulatory junction at the base of the brain that allows blood to be rerouted from other major vessels if one is compromised.
Redundant Supply: Even if one carotid artery is completely severed, the other carotid and both vertebral arteries continue to pump blood into this "circle," which then distributes it to the brain.
Consciousness vs. Pressure: Blood pressure does not drop to zero immediately. The heart continues to beat, and the remaining vessels struggle to maintain cerebral perfusion.
The Timeline: Instead of a "3-second" disappearance, the body typically enters a state of profound shock. This involves an intense physiological "fight or flight" response, including extreme panic, air hunger (gasping), and a massive surge of adrenaline. This state of conscious agony can last significantly longer than a few seconds as the brain fights to stay active.
The idea that it is a quick, numb transition is a dangerous misconception. The biological reality is a prolonged, violent struggle by your nervous system to stay alive.
