In the late '70s, Bolles predicted we would outgrow the idea that there were three stages (or three boxes) in our lifespan -– the learning stage, the work stage and the retirement stage. Bolles suggested that we were moving into a time when those stages would merge, and we would experience lifelong learning, work and play.
Industry and government reliance on outside contractors to conduct the continuing education of the workforce or to act as corrosion consultants is ultimately unsustainable as these outsiders learned their trade in the industries and agencies that are now buying in their services and that are no longer employing (and hence training) their successors. This situation is aggravated by the retirement of the few people with corrosion expertise and the near absence of corrosion engineering experience in new hires emerging from graduate and undergraduate engineering programs (Source: The National Academies).
When we deal with "life" assurance or extension of any asset, experience in approaching the problem decides the quality of finding feasible technology answers. We need to look at "History". How do we get this history? It is the knowledge of pioneers who have spent their entire career in corrosion science and engineering domain.
