As I understand it, at lethal currents, the path of the current is
just as important as the magnitude of the current. Any significant
current passing through the trunk of the body is bad news. That's
why the old electrician's advice of wearing shoes with rubber soles
and keeping one hand in a back pocket when working on circuits known
to present a hazard is just plain common sense.
Be careful out there.
