Slammed a car door shut once and started to walk away. Somebody pulled me back, I looked round, nobody there.
Then I realised the car door was properly shut and my fingers were inside the door. No pain, no feeling, fingers inside the door!
It was a shock and I was fearful what I would find when I opened the door. Plucked up courage, opened door, fingers bloodied and crushed but all there and bones intact. It was a tad painful when the door opened but the relief of not seeing fingers dropping on the ground was overwhelming.
Have been less careless with my extremities since then.
