With me it's more electronics and batteries that I affect. Electronics tend to die on me very quickly. If I hold a battery to my tongue to "test" it, I don't feel anything at all...till about 5 minutes later when my pulse jumps up and my head feels like it's going to explode, then I have to ground myself to release the energy....
If I pick up a remote, the TV will sometimes turn on or off before I even touch any of the buttons on the remote.
It's definitely affected by your mood - the more stressed/upset I am, the worse it gets. Once I calm down and breathe deeply, things settle back down to normal.
I get electric shocks from things all the time, too...regardless of what kind of shoes I'm wearing - I even get shocks on my fingers when I'm wearing gloves...gets annoying, but I assume we are this way for a reason :)
