	... And smart.

	When I'm working with live high voltage (including 110) I keep one
hand not just behind my back but in my pocket.  You look foolish, but it's
better than looking dead.  If you zap yourself and get knocked over, you
instinctively reach out to steady yourself with your other hand.  Keep in
mind that current flowing from hand to hand goes through your heart (I know
about skin effects, but wouldn't count on it).  If you happen to find that
grounded water pipe...

	With your other hand in your pocket, the extra time to pull it out
may be all you need to let go of the hot wire.  I'll gladly take the bump
on the head from hitting the floor rather than being fried.
