This is the way I look at it. When you write if-else-then statements all day long for a living you should probably be trained to think that way about everything. That's what happens to me all the time. I tend to consider the "else" and "else if" conditions almost instinctively. So, for example, if I am using a laptop at the diner table, I'll be sure to drape the power wires such that there's slack in the event of a tug. I'll also place a chair over the cable going to the wall so that there are very few ways for the kids to run into the cord and rip it out of the wall or computer.

I am, by no measure, infallible. Maybe I've just been lucky with notebooks.
