Had mine cut off once during an argument. I only recall being conscient or a few seconds, but my ex said I never shut up

...Asking for a friend....

I recall reading a supposedly factual story that occurred in the early 1600's .

Two priests were friends. One was condemned to death over his religious beliefs. They made a pact, that if the man about to die, could still see, after his head was cut off - he would blink his eyes three times. And apparently he did just that !
Later I read medical studies that confirmed that if there was sufficient blood flow in the brain - consciousness might possibly continue for a few seconds after the head is removed ...
Interesting thought anyway !

is there any positive reason to think about it? new first aid proceedures? instead lets just all imagine a happy dancing little group of 16 fur bergers with tiny little legs. overhead camera shotsd galore. call them the june taylor dancers. jackie gleason's old show. the good old days. .... its been 30 seconds, they still dance in my imagination, but the head has gone to her reward.

Back in 1799, a wilderness posse caught up with wanted serial killer Micajah Harpe aka "Big Harpe", outside of Hendersonville, Kentucky. After fatally wounding Harpe, the posse placed his head upon a tree stump, and started to cut it off with a knife. ( Being short of victuals, they were going to make head cheese from the outlaws head). At which point, Harpe rolled his eyes at them and snarled "Thou art a goddam rough butcher, but saw on, and be damned!". At that point, the head was partially severed. So I suppose it's possible for the victim to be partially conscious in a completely beheaded state. Personally, I like to imagine the head rolling around a bit, eyeballs full of wow, and perhaps making a gurgely gargelly sound!

May only be a few seconds to everyone else but to the beheaded it's a lifetime.

apparently up to 30 seconds or so?

Any volunteers?

interesting question

It depends on how quickly oxygenated blood leaks out dnayign the brain of oxygen.

Shock is a bitch, I doubt that if I'm beheaded I'll have the presence of mind to stick out my tongue in a final act of defiance.

I can't get the link open but there was a doctor who observed people beheaded by guillotine. Probably less than ten seconds since that is the amount of time you lose awareness when circulation is cut off by other means.

No time. Once the head is severed, there might be brain activity but no consciousness and that would be almost instant
