Gads. No, I'm implying that you are being a dense twit. More than one person schooled and skilled in working with electricity cautions about using a "Grounding" wire, and you choose to post to the contrary. You can ground the nozzle to the vaccum, but you will not remove the possibility of static discharge coming from you. The person using the vaccum, still needs to be wearing a "Static dissipation" strap, and not a grounding strap.
So, if you choose to ground yourself contrary to these warnings, then I'd say, let Darwin choose.
