As I said, for a better understanding of MS, there is a need to know the main reasons. I am expressing the etiology of MS. In explaining my theory, I can also clarify the issues that are considered as unknown to all about MS, and I prove it. I never blame neurologist scientists. I appreciate their some efforts. But, the whole human body is an outstanding engineering monument created and left to evolution. I just want them to see their perspective on MS from my point of view. Until today, no scientist has looked at MS like me. If they had, they would not start each time, saying, "The main cause of MS is unknown". Only artificial electromagnetic field sources are not reason of MS. In ancient times, the sources of the electromagnetic field for MS were human themselves and the natural e.m.f sources. Now all the electromagnetic field sources.
