@boomerexpert It is simple. If you get hereditary Gelsolin Amyloidosis, you will, as part of it, get an "amorphous (shapeless) deposit of dead protein prions (cells) in the top of your head. This will make you depressed and easily angered. It will affect everything you do. The source is the Gelsolin program and clinic at the University of Helsinki in Finland. Finland is apparently where Gelsolin started, and the Vikings spread it around the world.
