Heh.

There's another argument in favor of always
disconnecting power.

I do a lot of (non-pro) electronics work, but a wrist
strap is a bit much for my purposes.  Instead, I have
a power strip on my desk with a nice meaty machine
screw stuck in one of the ground holes.  I frequently
reach over and touch the screw, and then briefly touch
the chassis of my work at the same time, and then
generally stay in contact with the chassis while
working.  I repeat the process any time I've been out
of contact with my work for more than a few seconds.

I've been doing this for so long that it's become
habit.  Never smoked a chip yet.
