What Are Those Ugly Lines On My Fingernails?

As I’ve gotten older, those vertical ridges on my nails seem to be getting more and more prominent. I really noticed those ugly lines recently in the pictures on my pumpkin cheesecake dip recipe where my thumb is on full display holding a Nilla wafer. That’s when I decided to do some research to see if those ridges meant anything about my health, and if there was anything I could do to get rid of them.[mashshre]
