He also classified causes of death in a way that accounted for broader factors that determine health. Thus, effective, regular maintenance and testing is even more essential to continued operation when traditional “overdesign” cannot be relied on to overcome abnormal conditions. It is more about examining trends than it is about the medical aspects of a condition, although this does play a part.
