Why do fingernails not fall out?

Finger nails don’t fall out and this isn’t from google there is a little thing keeping your finger nails from not falling out it’s like glue keeping your fingernails from not falling out so if you cut her fingernails to deep they might fall out and they might turn black so aways let your mom cut your fingernails or someone else who is good at it. I hope this helps you
