How do you bite your nails?

To bite your nails effectively, it's best to, first, soften them. This is done by simply placing the nail in your mouth for about a minute or so first, though it's recommended that you nibble while waiting...to warm up.

Once softened enough start from the side, at the end of the nail, and get a good slice. It doesn't have to be a large slice. Once you have a good grip with your teeth (the 2nd incisors work best), tear it along to the middle as much as you can do.

Work the other side similarily.

Finally, go at the center taking bits off at a time.

The long term goal is to get them as short as possible, eventually turning the nail bed into smooth skin so that you can have at least 4 millimeters of skin at the tip. Try to get your nails down to about half their width and, when you do, you can finally call yourself a nail biter. Congratulations!
