This teen will almost certainly live and will probably make a reasonable recovery. Score another for the power of modern trauma medicine. Such medicine has made our homicide rate deceptively much lower (the 'conversion rate' of aggravated assault into being actually killed has fallen dramatically since the 1960s, see previous posts here on that topic). In addition, it has made the fatal accident rate much lower, and not just in automobile accidents. This plays into one of the strong meta-themes here at the Chariot: Improvements in Technology account for nearly all of the improvements in the lives of ordinary people, in many cases hiding massive increases of dysfunction caused by malgovernance.
