>>12455036Without freshly oxygenated blood flowing through the brain, you lose consciousness pretty quickly, basically just a few seconds.
See, for example, how long it takes for people to pass out in a choke hold.
Stories about beheaded people remaining "aware" are observers' misinterpretation of random nerves discharging.
Again, just look up videos of people getting choked out. When the blood stops flowing to the brain, you're gone and not coming back unless blood resumes flowing in short order.
