There is a big margin between what can be sensed by the skin and what
could kill you, or damage your body in any way.
But, of course you need to have a brain to do anything with electricity,
just like you need a brain to cross a street without getting killed.
Using normal precaution is of course necessary, like using a small battery
to drive this circuit, not the mains power. And start testing on a suitable
part of the body, like a leg.
