Why do our claws grow long?

The second is made up of what is called keratin. The horny material is a unique protein that is a little tough, but not as tough as bones or teeth.
Therefore, as you use your fingers, the nails gradually wear down, and the more you use your fingers, the more rapidly the nails wear down, and vice versa.
The finger with the fastest growing nail is the thumb, followed by the index finger, middle finger, ring finger, and little finger. The nails of children grow faster than those of adults.
These claws are made at the base. The nail is made at the base of the finger, and the amount of the worn out nail is sent out so that the nail does not run out. This is why the nails grow longer.
The white half-moon-shaped area at the base of the nail is the newly formed nail, and the size of this half-moon varies from person to person.
