So much talk, so little experiment.

Been following this thread, and decided to do this experiment. I
connected a DMM to one lead of a 9V battery, and did the "tongue test".
Battery, meter, and tongue form a simple circuit loop. Here's what I
found:

With an old, standard 9V battery (7V open circuit voltage), I get
0.7-0.8 mA.
With a relatively new lithium 9v battery (9.5V open circuit), I get 2
mA.

In both cases, you get that uncomfortable-but-bearable tingle.

I wonder if the I:V graph of a human tongue (or skin) is nonlinear. I
suspect so.
