Well, maybe not perfect yet, but almost. a new research reveals very interesting reasons for the nail biting habit, and it has nothing to do with nerves.
We always thought that people biting their nails are anxious people, nervous or at least showing bad manners. Apparently this negative conception we have is uncalled for, and we should learn some scientific facts before we form an opinion on what is the problem of the people displaying this ... well, quite a gross behavior, one must admit.
A study published in the Journal of Behavior Therapy Experimental Psychiatry sheds new light of what until now was considered a way to calm the nerve system or to deal with stress and anxiety. The research found that one of the most common reasons for nail biting is perfectionism, the strive to perfection. People who are perfectionist bite their nails to complete a work not properly done by their nail scissors.
Biting the nails is a fast and accessible way to deal with something that can drive nuts the people who like their life to be perfect and organized - sharp nail corners or nails in uneven length. The frustration created by a nail caught in your clothes can be immediately solved in the most creative and up-to-the-task little bite - how comfortable!Sources:
