Protect your fingernails - especially when playing frisbee! I lost a couple of nails yesterday evening while tossing a frisbee around with my dogs. I did not have any sort of coating on my nails. There's a really nice nail hardener with actual diamond chips in it. There are many different kinds, depending on what shape your nails are in (weak, paper thin, peel easily, etc.) so head out to the drugstore and find something to help your nails. I found some cool glow-in-the-dark nail polish for Halloween!
