You can withstand being at a high potential, as when you stand on an insulator and hold a Van de Graaf hood, but only because all of you is at that high potential. If any current at all passes through you (over the right path you can be killed by nanoamps) you will be toasted. If the nearest conductor decides to arc to the generator, you will likely have provided several feet of the path of least resistance, and you will be fried. In humid weather, current will pass through you and through the air and into any local grounded conductors; if you're lucky, the current won't concentrate around any nerves in your body (including muscle cells, which are mostly a special form of nerve). If you want to get really picky about it, current doesn't kill, voltage does, when it's produced by the uneven buildup of charge on the crucial structures of the nerves that regulate your heartbeat (again, including myocardial cells themselves). --Blair "Just defibrillating the newsgroup."
