Wow this is a very interesting thread. In regards to the monitors ....I never knew. That would explain what happened when I got bit a few weeks ago. I was at the store and like an idiot...I went to touch one from the front. He was so quick and got me on my finger. My fault!! But I did not even feel it....but it bled like crazy which I thought was so wierd. No other problems just blood running down my arm. Now I know. ;)
