I don’t know if this has anything to do with it. But what I do know is that stress, most of which is a mental creation based on fear of something that does not exist, causes the brain to freeze and stop functioning. Stress and fear cause the brain to be incapable of making clear decisions. Besides that the entire decision making process that all trades must be skilled at, requires the cooperation of several neurons working together in harmony.
