> The answer is "nothing"

Wait by “nothing” do you mean that there is no cause for the disease that the link you posted says has an unknown cause, or “nothing” do you mean that they don’t actually have anything wrong with them but you’re sharing a neat link about a disease that has an unknown cause?

I normally wouldn’t question an hour old throwaway that knows many neurologists, but what exactly are you applying the word “nothing” to here? You started with one statement, said that you don’t like a guy, and then wrote another statement that negates your first statement.

Like by “nothing” do you mean “I personally do not know, so my knowledge of what is causing this is nothing, but I want to share that I don’t like that one doctor”?
