LifeSIGNS will turn 21 years old in May. When we launched in 2002, the web was still young, and it seemed only American websites talked about self-injury. Now, there’s a better understanding, or at least a willingness to reference self-injury, across UK health websites. We might say that SIAD, Self-Injury Awareness Day, and the work of a multitude of researchers, health-care professionals, and passionate individuals have had an important impact on the country, and the world.
