Bad Habit... Do you know someone who nibble their fingernails? A habit that hard to outgrow... Thanks God i don't nibble my fingernails.. According to some Psychological Studies those who bit their fingernails are somehow battling from anxiety.. Anxiety is a feeling of worry,nervousness or unease..however when you regularly feels imminent levels of anxiety,it might become a medical disorder.. And it leads to "panic attack" when and how the situation overwhelmed a certain individual... My point here is sometimes we nibble our fingernails in different reasons not because of anxiety or whatsoever..but some nibble their fingernails to draw out some ideas from the corner of their brains.. Or just a past time that turned into a bad habit..
