You beautify them and decorate them or just keep them short and businesslike but one thing you can’t deny is that nails are the constant companions of humans. We are so accustomed to our nails that don’t think about the reason of their existence. Nails come handy in many mini projects and a survival tool for us. When an attacker or enemy grabs us and tries to strangle us or something we try to claw them and dig their skin with our nails. In such circumstances claws are used as weapons. Basically all mammals and primates have nails or claws. Evolution has changed much of our primal body parts but kept nails as they are.
