When I was kid, I was obsessed with my tapes. I would carry a boombox with me everywhere--especially when I went to play outside so I didn't have to go a moment without listening to Ace of Base. I know I wasn't alone in my devotion to cassettes. Museums and archives are pretty obsessed with tapes too, but for a slightly more important reason. That's the way a lot of our history--be it audio or video recordings--is stored. As I learned as a small child, tapes don't last forever, and if you're not careful they can get damaged, rendering them useless.
