I've heard that TV repairmen are famous for their one hand in pocket technique. Too many Caps to deal with...
When troubleshooting and more likely to get into a hot wire, I make sure the same hand is grounded (if possible) before touching a live, loose device or wire. I've had one too many low-resistance (wet, sweaty hands) through the heart hits and I don't like it one bit. Hurt for a few days...
I also rest my hand on the side of cabinets while inserting wire into grounding or neutral bars or inserting into CB's. I'd rather it take the short path to ground!
Failing all the above, I completely isolate myself from ground.
Oops! That coherent thing again...
