This is a remarkable story, about a chicken that lived for 18 months after it’s head was chopped off:

How the heck can this happen? The head contains the brain, and is the place where everything is controlled from. If you chop off a humans head, there may be some sign of life for a few seconds, but after that you’re no more.
What’s the deal with chickens? Is their brain surplus to requirments? Wouldn’t the pain and trauma of having your head chopped off, be enough to finish you off? Is this proof that the guilletine was a humane way to die?
In any case, the link above is worth checking out, as it appears to be a truthful story, and it’s is quite an amazing read.
