I don't think it's that simple. This theory does not account for genetics, lots North, less South (geographic factors) and other things. May be a by-product but doubt answer is this simple. All surgery is dangerous, already there are deaths with shunt displacement/ movement. I'm going to see what happens. While I always have a little hope on these things, I've seen too many become nothing. I predict this will overwhelmingly effective for some, destructive or non-effective for others.
