> Plus if there was significant charge in your body, or structure you would feel it. The point of my comment was that you probably come from a humid climate, because in dry climates, with plastic everywhere (as you correctly say, charge buildup from triboelectric effects), you do feel it, often. The whole industry behind ESD testing, protection, straps, sensors, and equipment wouldn't exist if charge buildup on humans were rare. As an electrical engineer, you should certainly know about the human body model [1] and have possibly even used an ESD gun to meet the relevant ESD standards (probably MIL-STD-883H for you, ANSI for my line of work). > any body charge someone does have is a result of the triboelectric effect, which is charge seperation, no charge is created I don't think this is relevant, since I'm not aware of a power source that creates charges, that a human would be intentionally exposed to. But, that doesn't matter, in this context. Where the +ve is at the time is irrelevant if the accumulation of -ve (or visa versa, I don't know anything about "grounding" stuff) on the body is what is claimed to cause the problems. The separation of that charge appears to be the the problem, with the "grounding" acting as a way to keep the "water level", rather than "eventually level". 1. https://en.wikipedia.org/wiki/Human-body_model https://en.wikipedia.org/wiki/Human-body_model
