I'd rather test it with a neon screwdriver.

We were told similar by our physics master, except I don't think the
advice was to regularly use the back of your hand instead of a neon
tester, just that if ever you were in a situation where you *had* to
find out whether something was live or not, and you had no alternative,
then use the back of your hand rather than pinching it between fingers,
or sticking your tongue on it!

I wonder how many kids of nowadays test PP3 batteries that way?
