do NOT bite your NAILS!

Apart from damaging your nails, there are germs under your fingernails, so when you bite them, those germs can go into your mouth. Think about all the icky stuff you touch all day long, like your baby sister's drool-dripping pacifier, your stinky gym socks, or people for instance do not wash their hands esp in the rest room! Ewwwww You don't want those nasty germs getting in your mouth... do you?
