Nine inch nails are nothing. A woman in Utah had nails that were almost 36 inches in length. I say had because she recently broke them in an accident.
She had not trimmed her nails since 1979 and had set the Guinness world record for the longest nail. Her nails were so long that they touched the ground. And, they were absolutely disgusting to look at.
Besides being ugly, they must have left her handicapped. How could she carry out normal every day activities? It would seem that no matter what she did, those nails would get in the way. Things like eating or getting dressed would be impaired.
Maybe now she can get back to normal, if she remembers what that was.
