Just got to like mother nature really knows how to build things.I took a tour of the Arapahoe Coroner's facility in Colorado. The X-Ray room was part of the tour and they had some pictures showing certain items found in bodies. One was an image of a skull with a tow hook embedded in it. I asked what happened and the answer was the guy was pulling a stump out of the ground using a vehicle and the chain snapped which caused the hook to go straight into his head. Be careful out there!
