If you're ever worried about getting shocked again two things:
You can buy a personal body ground that goes from your wrist to something metal that drains any excessive electricity that could run through your body. And second, make sure the hand you touch it with, the same side foot is on the ground, or the electricity will go through twards your other side passing through your heart. Either one of those could save your life. Speaking of the matter, anyone ever stick their finger in a christmas candle light socket before, I know I did.
