Yup and since humans trim or pick at their nails they don't get long enough to rip out as easily. I assume people with the extreme cases of YNS probably bleed

Yup and since humans trim or pick at their nails they don't get long enough to rip out as easily. I assume people with the extreme cases of YNS probably bleed when those gnarly nails get caught on things. Deer antlers shed even when they are tiny. I have a box full of their tiny ones that a neighbor turns into artwork.
