The Zero (of the pic) has to be connected also.  taking 2 resistors of 10K
will give a current of 6 mili-ampere.  That is well below the human
death-treshold of 30 mili's.  So it _should_ be ok to tuch anything on this
(the pic's) side of the construction.

But _I_ would not bet my life on it either !
