I also having similar problem. The thing is when ever I touch any metal part of a electrical components I will feel a small jolt of static. I just afraid that this might also be causing to get electrocuted by the lighting during thunderstorm or heavy raining. Is it possible that most of people who had been strike by lighting have this kind of problem?

Once when I was in Form 4 in the Physic class, I was turning on the power switch then I got electrocuted a bit. My teacher and classmate just laugh at me like nothing serious happened. phew.. lucky to be still alive after that shock.
