what cause's people to bite there nails and crack there bones like necks backs knuckles?

There are a few explanations. The first for mainly the cracking bones would be the positive feeling one mentally and physically perceives from cracking bones (technically not actually the bones). Because they associate the action with a positive feeling they do it more often.\n\nAnother comes from the stress release. In psychology there's a term called "Sublimation" in which someone will place their agression and stress into unrelated activities. This is an example in which someone might be stressed so they bite their nails or crack their fingers because they find this to be a pleasuring release of tension through the cracking sound or the light biting of the nail and removing it. \n\nAs long as people develop posotive associations with actions they'll continue to do it. At first the discovery is probably accidental but eventually a habit forms (the body seeks positive feelings and stress release).\n\nHope that helps

i myself had a horrid nail-biting habit until about two years ago.... when i got braces.\nmy orthodontist told me that my excessive nail-biting was causing my teeth to grow at an awkward position, and she gave me a bottle of clear nail polish that i was to wear at all times.\ni soon discovered that the nail polish tasted HORRIBLE when you put your mouth to it.... and that pretty much solved everything, since i didnt want a bad taste in my mouth every single day just because i wanted to get a part of my finger in my stomach....\ni think they sell that kind of nail polish at every drug store (CVS, Rite-aid.... etc) and you can ask them for it if you can't find it, cuz believe me, they WILL have it.\nif that doesn't work, another way that one of my friends (an excessive nail-biter also) solved this issue was to keep a fabric-covered hair elastic on her wrist, and whenever she involuntarily brought her nails to her teeth, she would sinap the elastic so that the slight physical pain would bring her back to reality and stop her from taking another bite. \nif you don't want to go that way, you could do it all in your head..... buy yourself a reward if you get through a month without biting your nails, another month, another reward... but that IS a little immature, and it's sorta the way a mother would train a little child, so i wouldn't suggest that.\nyou could also get your nails professionaly-painted, so prettily thaty your friend would NEVER wanna bite her nails again...\nother suggestions may be to:\nwear gloves, but that seems a bit weird, plus, inconvenient\nchew a lot of gum so you don't feel the urge to bite your nails when nervous\n\nhope this helps (for your friend) and that she gets rid of that habit!\nonce you stop biting your nails, you look back and think "why did I EVER do that?"\n\ngood luck!

I also bit my fingernails until well past the age of 40.  The only thing that made me stop that disgusting habit was to look closely at my nails when I was out in public.  Everyone I seemed to notice had beautiful, manicured nails and mine were stubs.  I did everything to hide them, but it's pretty hard to hide your hands.  I purchased a clear polish, and every time I thought about biting I would polish instead.  You have to combine that with the sheer willpower that you want your hands to look "presentable!"  Today my nails are strong and beautifully shaped, and I think of what I missed all those years by "nibbling" all the time!  Now I don't have to put my hands in my pockets...I'm proud of my nails and want everyone to see them!  Good luck.  You can do it!

Happened to a friend. Your teeth develop hairine cracks running vertically. As you continue to chew ice the cracks expand exposing nerves and causing pain. In time you will need                  crowns. It takes several years for that though.

Fingernails and Toenails are made from... hair! They are there to protect the sensitive nail bed underneath them. (Ever cut your nails too short... it hurts right? That nail bed isn't being protected like it should anymore!) Also, humans are animals, whether we like it or not, and most animals have nails to help them dig! Don't forget we used to not have grocery stores and such back in the stone age!

go to a chiro, too many people injure themselves or even worse attempting to crack their necks.

Because people tend to get nasty and angry with things they do not them themselves understand or participate in. So they lash out to make themselves heard instead of just biting their tongue and not showing that they don't know. What was it grandma use to say, ohh yeah. People might think your a fool but open your mouth and then they will know for sure.

many health conditions are reflected by nail changes...what you describe sounds like a result of trauma.

Because long nails can harbor bacteria, and nail polish flakes. (yuck!)

I think the biggest thing is it bothers other people.  Health wise, I don't know.  I've been cracking my knuckles for as long as I can remember, and I've never had any problems.

No,that is an impossible reason..There's a condition,usually genetic(that is when is transmitted from genaration to genaration),which cause those nasty inproper grow of the nails..See a good specialist,because in the long run you may experience nasty outcomes if neglected..Good luck!!!

Usually it is caused by stress or sometimes restorations that are too high.  A bite splint is recommended for grinding at night.

Well damn I can't stop! I even bite my toe nails on occasion but not as much as my fingernails.  I get embarrassed cause all my friends have such nicer nails.  At the moment I'm trying to conciously not bite them.  I've been biting all my life and they are really thin and weak so that sucks.\nAnyway screw this person. I have depression and well get very bad anxiety attacks. The people who get at you for your nails have no lives.
