Human Bio-electrical energy

Hey, did you know I accidentaly did last night a circular move of my fingers over chest and unwillingly I was electrically shocked! No kidding!
It usually happens if rubbed over sport plastic costumes but the thing I was wearing was not plastic in origin but more over plain simple daily material, and what's more, I think it was in middair circular move. I think it must've been a interconnected circle with my electrical devices as I were on PC and tapping on keyboard and moving my other hands'fingers circulary on chest! It is called static energy or electricity. You could always try this home and also test other things like gravity with three stone, one circling the other two who are put together in that so the stone circling is always between them. The effect is simply attraction between the two who you try to take apart!
