I did not really dissect it but I did try to break it apart but it could not be broken, unlike the other rope-like stuff which fell apart once I poked it with the straw.
I spoke to the program manager and he said it might be one segment of a tapeworm. But I have never seem to have any of the symptoms before which he asked me about. He said people with Tapeworm normally will have (1)bad breath and/or (2)feel hungry easily, irregardless of the amount eaten and/or (3)itchy anus.
I will see if anything like this come out in the next colonic.
