Oh, I remember hearing about this woman. She has a genetic disorder called Marfan lipodystrophy syndrome, which prevents her from storing fat and gaining weight, so this means that she has almost no subcutaneous fat at all and only weighs 60-something pounds giving her an "emaciated" appearance and has been blind in one eye since she was a child as the myelin (fatty "insulation" layer) surrounding the optic nerve broke down leading to the nerve to effectively cease functioning.
Oddly enough, she is a motivational speaker.
