Not Worth It
Five pounds may not seem like a lot of weight but having it around your neck 24 hours a day for 7 days will surely be exhausting. It may seem that to other people, it is some kind of torture.
Medical Issues
According to Dr. Jonathan Nissanoff, an orthopedic surgeon from Southern California, doing this kind of thing might cause severe injuries in the neck that is why he does not recommend doing it. He also added that Sydney’s neck will not stretch anymore, only her skin because she is already a fully grown woman.
