It is a serious muscle disorder, I didn't wanta make any comparison, to parkinson thought it should stand on its own too. I don't take light of it though. It can affect any muscle group. People have to be on respirators in extreme cases, cause of breathing, and the coordination can put you into wheel chairs. Our muscles are amazing and complicated and its communication between the brain and the muscle. It does worry me, and that may sound selfish, but its life impacting, and likely not to go away.
