They are evolutionarily related to claws, which get worn down when scratching things. Therefore we regenerate them by growing them out at the base.

Because when keratin cells die they go into your nail root and the old cells get pushed by the new cells that come from the root.

So you can bite them off. And mean women can scratch you with them, Obviously.

They seek freedom, opportunity, boogers.

I learned this in 2nd grade.
