 Once a person's neck has adjusted to the neck rings, they have to leave the neck rings on permanently.Because the rings have been on these women for such a long time, this weakens the neck muscles, rendering the neck essentially unable to support itself.The neck muscles will tire quickly and not be able to carry the weight of the head; in other words, when the neck is no longer able to fulfill its function it is very likely that it will collapse, thus resulting in suffocation.
