A habit is something that is a settled or regular tendency or practice, especially one that is hard to give up.

Every person has weird quirks or habits that are normal to them. There are a couple of these habits that are more common than others.

You probably know someone who has the habit of biting their nails, playing with their hair, bouncing their legs, or picking at scabs. These are weird things to do, if you think about it, but people don’t even think about it while they are doing it.

Habits can be not so good for people, such as picking at scabs or pulling out hair; but most habits are harmless and at most annoying to others, such as bouncing your legs, or tapping your fingers.

These are normal facts of life, even if they are not normal themselves.
