I may actually have a useful mutation. The entire reason I went into IT is because I have this weird ability to either just stand near malfunctioning electronics and they start working again or to take anything electronic apart, not have a clue what is wrong, put it back together and it works.
I'm not the only one that noticed this mutation. My Mom used to joke about it when I was a kid, to the point where neighbors would bring over their stereos, walkmans, and computers for me to look at. I even have a consulting job once a month (for $150 an hr) where I run the backups at a lawyers office and sit and read a book while they are running. My client requested this because whenever I'm around, the backups go flawlessly, whenever I'm not around, they fail and something else goes wrong where they need the backups.
I have met other people with this ability too. Most of them gravitate to the IT field. People in our office will even request one of us to be around when they are running monthly reports (or something of that nature), just so nothing goes wrong. In our office its called "the IT effect" and means that when someone from IT is around, computer problems mysteriously disappear.
