Quote - As far as bodies walking without heads - It's "possible."

Completely right ... but this belongs to persons beheaded in a battle for example. So they have been walking while killed and the muscles followed and worked in the same manner as before for some seconds.

There was some 20 year's back a report of an accident between a truck and a motorcyclist. The truck was loaded with steal slabs. One of them slipped aside while the motorcyclist overhauled the truck and he was straight beheaded. But he finished overhauling, sitting upright on his engine.
Ok, next curve he didn't master and the truck was in trench just before ... poor driver got the shock of his life ...

Quote - Then... there's the true story of Mike the Headless Chicken. :)

I know the story ... and have to laugh everytime. It remembers me to my youth there I used to sail on a lake nearby. The chimney sweeper of the village at the lake lived in a house around the corner and we meet often. Once he got a chicken from a farmer ... small trade between craftsmen, you know. The farmer had told him to hold the chicken tight while killing it AND also some time more. But our friend ... ok, he went to his garage doorway, killed the chicken and laid it  down ... and the chicken, headless, run up and away, straight into the garage.
The garage was newly painted just the day before ... clean bright white ... WHAT a real mess, looked like a big massacre ... :laugh:

So headless chickens are no point of discussion ... though the time mike did his headless live is really astonishing. Maybe there is some truth in the story that some people are only having their head to avoid to carry their hat in the hand ... :lol:
