@golden I'm finding this quite interesting but unfortunately go a lot of other stuff going on at the moment which I need to address, but I will come back to it and look at the links. I suffer terrible from getting shocks from cars, metal bits in shops, lift buttons, shopping trolleys etc. they can be big shocks as well making me shout, I mean have you ever seen anyone at a supermarket jumping back from a trolley shouting aahhhhh? !!!!!!!!
