I spent a week off work after forgetting
just that once to put on the safety glasses when taking a little nick off a piece of steel with a bench grinder. Ditto on the "head in vice ... scalpel, etc" story.
More recently, I was working in a dodgy part of town in a rented shed, and because of the local ...errrm ... nightlife ... decided putting the car inside the shed would be better. I happily drop-sawed, welded, ground away for a few hours, with all my safety gear on and totally absorbed in my work, not even thinking about where the car was parked and where all those sparks were going ....

So now I have a Ford station wagon on offer, cheap, needs a new paint job and windscreen but drives well .... !
Lesson learned!
