The static current is a funny problem here. I don't remember if I ever wrote you people about it. Being near the pole, our body develops static current due to movements in closed areas, working in labs with equipments having magnets or electro-magnets, or wearing clothes containing synthetic fibres like nylon etc. The problem gets worse during winter when members are confined indoors most of the time. All the labs containing computers, communication equipments etc have a warning at the door to discharge oneself of charge before entering the lab by touching a copper wire hanging outside. In spite of that the display function of all the phones here with caller ID has been damaged. People avoid a touching or handshake with certain members who are known to carry more charge because of their working with charge generating equipments. It gives a shock to the other people which is audible at a distance; while one is wincing with that momentary shock all other burst into laughter. I too have a one or two pieces of garments that generate more charge than others; esp., my favourite front open black sweater. I am sure to get these shocks many times a day. So on days when I am wearing it, I keep on touching metallic surface periodically so as not to allow more charge to accumulate. I have to be careful when working with my laptop.
