The research was commissioned to investigate why some people who worked on the deseal/reseal project on F111 aircraft, "suffered significant health impacts — such as depression, anxiety, erectile dysfunction, memory loss, skin conditions, gastro-intestinal problems and an increased risk of cancer — while others did not".
Maybe because in *any* random sample of people, some will suffer significant health impacts such as depression, anxiety, erectile dysfunction, memory loss, skin conditions, gastro-intestinal problems and cancer, while others will not?
