Why is it bad to bite our fingernails? Is there certain diseases we might pick up if we keep biting our fingernails? Is it just seen as nasty like picking your nose?

Biting fingernails is also bad for the teeth. Nails are hard and will impart a lot of stress on the enamel, teeth, and gums. It can lead to early wearing and teeth issues (which can eventually lead to additional infections and diseases).
