I'm an engineer, so my brain floods with happy chemicals when I'm able to identify a problem, figure out what's wrong, and solve it.  For example, when my DVD player stopped working, it was fun to dig around in the pile of wires behind the TV and find out that my rabbit chewed the hell out of everything including the power cable for the DVD player, which was surprisingly easily fixed with electrical tape.  But sometimes I'm ok when that middle step gets skipped, and when the problem just magically goes away.  For example, my car's check engine light was on, so I took it to AutoZone to get a free error code reading (that's seriously a great deal), and the sales guy interpreted the various codes for me with some complicated automotive verbiage.  He said I'd need to go to a special place to get it fixed, and it would cost lots of money just for them to figure out what the problem was.  Being a cheap bastard, I looked up the error codes online, and one of the solutions was to remove and replace the gas cap.  I tried it, and it worked, and I haven't seen the check engine light since.  But just because I solved the problem, it doesn't mean I actually fixed what was wrong. #technology
