What is it about nails on a chalkboard that make just about everyone cringe? Any scientific reason?

The frequency of the sound stimulates the nervous system causing an involuntary muscular reaction at the base of the neck. This has the effect of causing you to shudder; making your spine tingle; putting your teeth on edge, or a combination of all three.

Why yes I do. It is on my pointer finger. Everythime I get one I want to bite it off and then it hurts. I think hangnails hurt. I have a booboo.

Because their butts are flabby and not in shape. Shouldn't shake at all when erasing a chalk board. Case of cottage cheese syndrome.

Peoples' silly "sensitivities" are so easily bruised.  \n\nBTW: Your answer about "diving in" was amusing!

If there are a lot of deep scratches in the back of you're bord and they're through the wax. Mostly too when you don't feel any wax, just like you feel that is all off. It is time to sharpen it, when you move you're nail over the side off the board and nothing scrapes off your nail, then it needs to sharpend.

Some people bite their nails simply as a bad habit and they have to consciously make the effort to stop.\n\nOther people, the ones who get down to bare bleeding skin, may be suffering from depression or something similar.  I used to be this person, I was biting my nails down to the nubbins to (unconciously) cause myself physical pain in order to cover up emotional pain.  After spending some time in therapy I was able to find better ways of dealing with things and now I have lovely nails!\n\nBy the way, this second example of nail chewing is a very similar behavior to people who cut or otherwise hurt themselves... the physical pain is easier to deal with than emotional pain.

It really irritates me.  I also hate tcapitalizinghorthand (b4 for before, 2 for to, etc).\n\nI think it is lack of education.  Sad sad day for us all.\n\nYou know what else irritates me?  Not captilizing your I's.  Also, when they spell don't spell "a lot" correctly.  There is a space people.

Yes indeed. The sad thing is, most of the people who are displaying here wouldn't admit to it if you were pulling their fingernails out by the roots (now there's a thought).  I don't get it myself, but yeah they are annoying.

when someone scratches their fingernails on the chalk board, cold air, and when someone scratches my back.

There's this stuff at Wal Mart in the nail care aisle that you put on your nails and it tastes like crap.  So if you bite your nail, you get this horrible taste.  Eventually, you'll condition yourself that biting nails=nasty taste.

well, to each his own. If you like the gothic thing, well okay, that is you and that is whoever else. Everyone is different and everyone has their own preferences that is what makes our world so special and so wonderful. \n\nSome people just have their opinions about things and just have to rudely and openly voice themselves to others. Those are the types of people that have issues and they think that picking on someone else is going to make them look better when in reality, in my eyes it belittles their character even more. \n\nLet it go. :) You are who you are and if that is what you like, well then GO FOR IT!!!!!!!! Imagine what the world would be like if we were all identical :P \n\nGood luck. Smile:) and ignore the sharp tongues ;)

I can only assume that the teacher doesn't feel that you having to write on the chalkboard as a form of punishment is wasting chalk -- obvioiusly you do feel it was a waste of chalk which means you don't feel as if that exercise was punishment.

That's funny, about your nails, but I know what you are saying. I used to be critical of others spelling. But, sometimes, your brain answers faster than you can type and that's the reason for the mistakes. It is rather humbling when I would make mistakes, because spelling is my strongest English skill. I think it has to do with wanting to hurry and get your answer submitted quickly. So, needless to say, I'm alot more understanding of peoples' mistakes now.

The nail is important in protecting the sensitive nerve-endings, and this needs to be addressed with a doctor in order to help her develop normally.\n\nPossible causes:\n1. Fungal infection.\n2. Nervous system disorder.\n3. Nutritional deficiency.\n4. Mineral deficiency.\n5. Genetics.\n6. Compulsive behavior (Tourette's - no, not as in swearing; most people with Tourette's compulsively pick at some part of the body)\n7. Defect in the nailbed or nail matrix.\n\nStart with a pediatrician and have him or her refer you to a good dermatologist.
