[sci.electronics] picture tube static / cable converter ground

   Recently, while reconnecting my VCR to my TV, I had my hand resting on the
picture tube for support, and in reaching back, brushed the exposed metal on
the corner of the cable box.  (The outside of the box is painted, but at the
corner, there is a tiny amount where the bent metal is exposed.).. I assume
this to be a chassis ground...it's a new Jerrold, if anyone's interested.
Anyway, the TV was off and had a reasonable amount of static charge on its
25" screen.  I got a shock that, although not too bad, caught me completely
by surprise.  Usually I am fully aware of being in a situation where something
like that might happen.  

   Anyway, my real question:  Does this present any kind of electrical hazard,
given the ease of reproduction (I repeated it a few times...call me a sado-
masochist.)?  What would have happened if I was wearing a pacemaker?  Or, for
that matter, if I was more sensitive to electric shock?  (I tend to be very in-
sensitive, and work on telephone pairs and even 115vAC with relative impunity.
I guess I'm a good insulator...I've been told that before.  On the other hand,
I've also been called "highly impedant"...  take your pick... :-)
