What humidity does to your neck

Have you even wonder what Humidity can do to the neck of your guitar other than the neck having a pretty obvious warp? Look at the above picture for clue. This is a very good example of the wood shrinking in colder and dryer climate places having the fret ends popping out at the side. This is especially dangerous to us players as the fret ends in such a case is actually sharp and can cut us when we are playing the guitar. Next time you pick up a guitar, make sure that the fret ends aren't popping out like this.
