Mental Recycle Bin

Why is it that we tend to retain so much useless information and be so proud of ourselves when we can pass it along to other people? Generally labled as "trivia", this info can cover so many broad subjects and content but never really contribute to the true meaning of something or its outcome. Why do we remember such insignificant things as the clothes we were wearing or what we were watching when we heard the news of 9/11? Why do I know that I was home from school with my mom for a snow day and still in my pjs when the space shuttle Challenger exploded? Yet, I don't remember much about the actual event itself, probably because I was only 7 years old. I truly believe that God has a sense of humor. He has to be laughing at me when he sees me straining to remember something of real importance and I can't even catch a glimpse of it in my mind, as if I had never been told or learned it at all. Yet in the next conversation, I can be the center of attention as I spout out lines from National Lampoon's Christmas Vacation. So frustrating. Where is that switch in my brain that allows this to happen? Is my mind so overloaded that anymore information will blow a fuse? That's how I often feel. Like I can't even think straight and if one more person asks me to recall something, I'll lose what I have left of my mind. My point is, why don't we as humans have a recyle bin that works like a computer? The ability to "delete" certain information to make room for new, but recycle it if I ever find that I need it again. Wouldn't that be an amazing feature? Perhaps that's why the computer outsmarts me. It has those features. You can find almost any information you want online; even that worthless trivia.
