[Gremlin]

Some while ago I had a serious back operation and to help me get around I bought a small invalid scooter, just big enough to fit in the boot of the car. I only used it on odd occasions but a few times I took it to Blackburn Hospital when I was visiting my wife who was as far away from the entrance as one could get.

I drove through the corridors and when I pressed the lift button I thought my arm was broken with the static shock. When I returned I used a glove to press the button. It seems the rubber tyres on the floor must have built up some static and I earthed myself with the metal button on the lift door entrance. It never happened to people walking who did the pressing. The scooter is still in my shed and in mint condition but saved for later in my twighlight years.
Dodgy stuff electricity if you don't know what you are doing and my advice is the same as less, leave it to the people who get paid to take risks. It's not that long ago I passed my City and Guilds in Radio Electronics and people say " I don't know how you can mess with electricity", my reply is, " I don't, I only mess with wires".
