Not only is dust annoying, it's gross. That seemingly innocuous crap that builds up on the shelf around your nicknacks and on your stereo is a conglomeration of nastiness. If you take a close look at dust you'll not only find dirt, you'll also find sloughed dead skin, hair, pollen, plant fibers, pet dander, dust mite carcasses, dust mite feces, bits of spider web, and more. What's worse is that you can never get rid of it completely. There are a number of things you can do to significantly reduce dust in the home, but it will always be there.
Static is generated on the surface of our bodies constantly. This static is lost when we ground ourselves out or by quickly discharging it to another object or, in many cases, to another person. The quick discharge is the zap. Human beings are only good electrostatic generators when we are well insulated. To be well insulated, at least in electrostatic terminology, means that there is something keeping us from grounding out. When we ground out, we lose our surface charge. As insulators, we don't conduct electricity well, but we can generate and hold onto it very well.
Are you sniffling and sneezing during the winter and you don't know why? It could be that you have an allergy to certain molds. Once in a while a mold problem in the home, which can be controlled, is the cause of allergies—kind of like dust. Perhaps you're not suffering from mold allergies, but you're looking at your bathroom wondering how it turned into a science project so quickly?
