True story from the forensic files .....Crankyfeet said:rotfl...
They may evolve a defense mechanism. Initially it could be like African buffalo... they herd in a circle facing outwards... and maybe they get even fatter...so it becomes impossible to penetrate anything fatally deep enough....
One of the pathologists at a conference I went to recently was telling the story of the bloke who stabbed his girlfriend 134 times. However, she was so fat that only 5 of the wounds actually penetrated deeply enough to cause any damage. What killed her was a nick to one of the major arteries which nobody at the hospital where she was taken picked up and she died one week after the initial injury.
Apparently all the bloke could say to the police over and over when asked why he stabbed her so many times was - "She wouldn't ****ing die, she just wouldn't ****ing die"
