It is refreshing that SOMEONE seems to know this. However, I have a couple
of reservations about your second sentence. The resistance of the body is
almost entirely in the skin, which is quite high when dry. If, somehow, you
got across some voltage while wet, or perhaps bleeding from an accident, the
resistance could be very much lower. Secondly, the amount of current that
can be lethal depends on the path through the body. The worst would be
across the shoulders, which places the heart in the circuit. The path from
one hand to the other, or from one hand to some lower part of the body could
also be quite dangerous.



Actually either arm to the opposite leg is supposed to be the
worst. I've gotten some shocks that get into the letal level,
but it just happened to hit my muscles in the way that threw me
off the circuit instead of the opposite. The worst is the
condition of being "tetanized" where your muscles lock you on
the circuit, and it can actually be very hard for insulated
persons to knok you free with a hot stick or similar tool.
One guy at work was using a bad hot stick, and got tetanized
while flipping a 4160 V switch and his safety watcher had to
beat the CRAP out of him to break the connection.

(I don't work on this high tension stuff, but electronics, but I
am aware of the hazards.)
