Now how do I know these things for sure? Easy, they got a little too arrogant in their attacks, thinking we are too stupid to figure it out. It is one thing if two related people acquire the same symptoms but when your spouse, pets, and neighbors do, then what do you say? Logical thinking, it is environmental as that is the common denominator. I assert that MS, Multiple Sclerosis, is nothing more than people being attack by Cyanide which destroys muscle and nerve tissues down to the bone. Because eyes have moisture and can secret proteins, comes blurry vision until it is completely lost as the chemical also destroys nerve endings in the eyes. If you get it on your cloths it is still dangerous, but when it is on the pants then the toxins are forced into the legs by normal sitting, walking, and movements. As for the head and spine area, this is because these toxins are misted in air pathways that land on mainly on the back and head. Droplets that land on the head also cause migraine and neurological disorders and can travel down to optic nerves, which is why people with migraines also complain with that type of pain.
