What benefit could nail-biting possibly give you, right?? Though it’s addictive, no one likes the thought of sticking grubby mitts into their mouths, not to mention the pain that comes with biting off too much and ending up with scraggly-looking nails that no amount of nail polish can render presentable. Been there, I get you.Surprise, surprise. That very thing about nail-biting that makes it so gross is actually what makes it somewhat good for you. Apparently, introducing germs into your body a little bit at a time can build up your immunity to the stuff. Huh, who would have thought?
