It's not clean till it's CSI clean!

If I were honest with myself I'd have to admit that I watch too much TV.  Most of the shows that I watch DO have some educational value, but you could say that about any TV show today.  I've even learned a few things from watching the Simpsons.  By far, my favorite TV shows are true crime stories.  Forensic Files.  Body Of Evidence.  Cold Case Files.  The System.  Although it's fascinating to watch how the detectives gather scientific evidence with state of the art equipment, how can I justify my interest in such shows?  Will this knowledge help me in my profession?  I'm a nurse, more specifically a nursing supervisor, so unless knowing how to conduct a ballistics test on various fire arms will help me find a nurse to work in the ICU tonight, that's not information I can use.  How about at home?  No matter how much I fantasize, when I dust my living room... it's not for fingerprints.  Socially, I can see where a little forensic knowledge might possibly alienate you.  It's just not polite to 'interrogate' the neighbors, and they DO notice when you're making mental notes on what brand of cigarettes they smoke, what size shoes they wear, and the existence and location of any tattoos they might have.  Looking back on my life experience I realize that I have never been called upon to pick someone out of a line up, describe a suspect to a sketch artist, or even look through any mug shots.  It would be much more rewarding for me to watch a TV program on health issues or home remodeling.  So why do I get such satisfaction knowing that when I'm finished cleaning, if a team of forensic scientists were to come to my house, the only dirt and fibers obtained at MY crime scene would have to be left by the perpetrator himself?  Do I worry that watching all these crime stories might make me paranoid?  Not at all.  I don't think it's asking too much for immediate family members and close friends to provide a small DNA sample for possible future forensic comparison.  Do you?
