How old am I?

This morning, Kelsey asked, "Mommy, what is a tape recorder?" I must say, that moment made me feel way older than it ought to have!  She is getting into music, asks to listen to my IPOD and even asks me to turn the radio to country music.  It is a little difficult to find a country station in the Seattle Area.  Anyway, I don't even think you can buy a tape recorder anymore, can you?
