A couple weeks back I remember the case when someone bleached her home because she feared she could catch the viruses on her computer. There are many people who do, for the lack of a better word, rituals with their computers because they can't figure out their wi-fi radio tales some time to grab the local network signal. They do it because they did it once and it worked and they have no idea it had nothing to do with the problem they were trying to solve.
A basic understanding of technology is increasingly important.
