Do you have any habits for stress-relieving? Such as nail-biting, thumb-sucking, nose-picking, hair-twisting or pulling, tooth-grinding and picking at skin. Nail-biting is the most common of the typical “nervous habits”. Some kids and adults may bite their nails when they are in times of stress or excitement, or in times of boredom or inactivity. But it’s not a healthy habit.
