There is nothing worse than a college dorm refrigerator. Midway through a semester you would swear that most of the leftovers had grown fur to combat the cold. The milk carton that gets pushed to the back of the shelf contains a substance akin to yogurt with a smell that redefines the meaning of retched. Eventually the only solution was to plug your nose, shovel everything out and start all over again. Unfortunately if computers could emanate an odor most of us wouldn't be able to sit down if front of them for more than a few minutes without activating our gag reflex.
Computers seem to gather files faster than garbage gathers flies.
My six gig hard drive currently boasts over 39,000 files. Some of those files are older than my kids' ages added together. But I've only had the computer for a year. It's always amazing how fast a new computer runs. Unfortunately the first thing that we usually do is start copying files from our last computer.
