wearing slippers on heavy carpet floor, fleecy jumper, chair that regularily gives me shocks from static... half heartedly touch the case chassis occasionally, although kind of hard not to anyway. none of this being pansy with pcb either, they do take a fair bit of abuse. no i havent killed anything yet and yes i probably will regret it at some point, but tbh otherwise youre there all day anyway and things held too carefully tend to get dropped.
oh yeah but DONT place pcb's on top of anti static bag, they work on the thatfrenchphysicistbloke-cage principle, theyre specifically made for any electric current to pass on the outside of the bag.
