Unfortunately because everyone says it, some people make invalid conclusions.....

Yes, it is the current that the body receives that will determine the severity of the shock. 100mA for a short time will most likely be lethal, safety switches are set to trip by 30mA and must act within 30ms. Do appreciate that the current required to kill someone, 0.1A, is not very much at all, even a tiny AAA battery can do better than that.

Because the human skin has quite a high contact resistance, voltages of below 50V generally are not high enough to produce a damaging amount of current. No, you wont be electrocuted by touching a AAA or even a 12V battery rated at 750CCA, the current that is able to flow through our bodies isnt high enough.
Human contact resistance of course decreases when the skin is wet and electrocution even as low as 50V is possible if wires were to be held in wet hands. On the other hand, if your skin is dried with chalk etc, contact resistance may be so high that even 240V would only produce a tingle.....dont try this at home folks.

Yes my parents are technologically challenged too, programming a vcr their non specialty.....some people just never get it, love the scene in city slickers on that one.
