When you let your computer keep track of statistics and other minutia, you can end up with some really interesting factoids.
Like this, for instance: Tonight I opened up the properties sheet on the spreadsheet file that I use for bookkeeping. By doing so, I learned I had spent a total of 165 hours editing that file since creating it on February 14, 1999. That's 6.875 days, or if I was only doing "work weeks," that's almost a month of non-stop work. But, when all is said and done, it's only about 1.7 hours per month. Not too bad, considering. Oh, and the file had been saved 855 times.
So, what interesting facts about your life has your computer (either intentionally, or otherwise) recorded about you?
