Re: When you get older your fingers become less conductive.
Well I'm in my sixties and while fiddling with some net-type fairy lights in the front garden last night I located a bare wire with the pad of my ring finger.
A few seconds hopping around the lawn shouting "aggle-aggle-aggle" have given me the encouraging sign that the old fingers are pretty much as conductive as they used to be.
True, the net lights were torn from the deck rails and dragged around the lawn before being ripped out of the supply outlet in a contra-indicated manner, all to the cruel laughter of the neighbors, but the lights were faulty anyway, the neighbors are gits & can suck my manservant and you can't have everything.
