IF you are properly grounded, once you grab the handle of the
soldering iron it will within seconds no longer be at 1000 volts
potential. Maybe you should also read your Ansi Standards a bit more
and understand static prevention. Once you are grounded touching any
other ungrounded object will dissapate the charge built in it. That
charge will drain through your body to ground within a very short
period.
Besides most ICs can shrug off 1KV with no damage. It is neat to see
what a 15KV jolt does to the poly layers and the protective zeners on
an IC. If you ever get a chance to do some electron scanning of static
damage to the die pad area of an IC, do so. It is a really neat to see
what 15KV can do.

you evidently have never worked for a large company such as Northern
Telecom. If you mentioned you understanding of ESD during an
interview they would laugh you out the door. You are 30 years behind
in your ESD knowledge.
