i was working under my car changing the speedo gear, i sneezed and cracked my head on the floorpan, instant reaction was to pull my head away and i cracked the back of my head on the cement, then almost cracked my head again on the floor, ouch

few years back a mate was pulling the steering wheel off his commodore, he forgot to leave the nut on a few threads, he got a sore nose and a black eye when the wheel let go and hit his head

another time he was working under the bonnet of the same vk and he bumped the bonnet rod, bonnet came down hard on the back of his head and forced him into the radiator on the forehead, 6 stitches to the back of his head and 3 in the front

he liked a waccy tobaccy smoke now and then, came back to work from lunch after a session, he was a welder
he was playing with the mig, in his own world, started feeding the wire out in circles around his head, got about 4 laps around and the wire arced out on the welding bench and started to glow red,
got 3 deep wire burns across the back of his neck.
it straightened him up pretty quick and would have had trouble explaining to the boss what had happened.
