"How the heck did that happen?" Injuries

Between cars and maintenance job, way too many..
But one worth mentioning. Have a scar on outside of my wrist from about 30 years ago. Winter day, six plus inches of snow and i was out in a yard getting a drivers mirror for my (long gone) 71 cuda. Reaching my right hand inside of the door, never felt ithe sheet metal cut cause my hands were so cold. My buddy says "your bleeding". I licked the blood off so it wouldnt get on my coat. I thought he was going to pass out. I kept working and got the mirror. LOL
