This looks somewhat similar in idea to the HANS head and neck support device used in motorsport but a lot smaller. It was invented about a decade before its widespread, initially drivers thought it was clunky and restricting. It was adopted and officially mandated (in both, FIA and major American motorsports) after another preventable death from a basilar skull fracture caused by a rapid jerk on the head upon impact.<p>Some professional athletes sacrifice their health for the entertainment of others (in injuries as well as unheatlhy training regime and doping). I&#x27;m all for making sports safer but as the audience we should also align our expectations to reduce the demand for dangerous feats in sports and entertainment.
