"Shell Shock" of course being the feeling when you discover that you are not using bash 4+ === End joke section === Shell shock has a genuinely complex and interesting history. It has described different conditions, had different connotations and value judgements, and had different supposed causes over time. As I understand it, shell shock has at least two very real components: Traumatic brain injury and Post traumatic stress disorder - they are often found together, and they act together to make things much worse than either by themselves. Mainstream understanding of the harm of repeated mild traumatic brain injury is very recent, relatively speaking.
