Some years ago I was preparing to remove the battery from a car.
I remember watching something on Discovery.. the program about the scotish mechanic in spain? Well the useless lad who was there. He charged a battery while it was still in the car, when time can to stop the charging, he unclipped the leads before removing the plug from the wall.
On the program, they are all standing around with the camera on the group and there's a muffled bang behind them with him walking straight to the toilet... they all followed him there and he was washing acid and extracting bits of plastic off himself.
That coulda been worse!
I remember I once tried to stop a circular saw with a finger nail... I nearly fainted after that one. Shock! I only lost half the nail but felt as weak as a kitten. [I didn't really try to stop it, I was putting it down and the finger came in contact with the still spinning blade]
My luckiest escape was on a building site: I'm on a scaffold at bedroom window-ledge height, it's a housing estate and all the area directly under the scaffold was full of both full and open brick & slate pallets, planks, wood, and all sorts of cxxp. I'm up there getting set up to do my work and went to put the guard rail back on as a roofer had unclipped 1 end to lean his ladder against the gutter.
Just as I'm about the push the rail back into place, the plank went from under me and I swear to god the only bare patch of soil under there was a big as a telephone book and I landed feet first in it. Talk about sureal... 1 second earlier I was up there, now I'm looking at a corner of a the pallet of bricks like 4 inches in front of me crown jewels. I looked around to see if anyone was running to see how I was but no-one saw me. I had to go looking for some sympathy.
What saved me was I still had hold of the guard rail as I went and my instincts gripped that rail for dear life and bent it in a big 'r' in my graceful arc down... and that's how I landed after the planks*... it broke my fall. I was blxxdy lucky that day, I can tell ya. All I had was scuffed palms as the rail had hard sand/cement drops on it and they was like sandpaper on me poor hands.
* this is where the pallets and shxxe saved me as the planks must have fell the other side of all the cxxp and so couldn't bounce back over and hit me.
It was just a surreal experience.
