The fibers are VERY real and can cause a lot of pain if they build up in your body. Some people can not get rid of them as easily as others...there is no telling what they are being used for...I've had some problems with Morgellon's type symptoms in the past, especially with my skin...after lots and lots of detoxing I don't seem to have the same problems I used to have. I know you probably can't get rid of all of them, but its important to try and detox from them on a regular basis.
