Just to expand on RayRapp's point at #34, it seems that many of our experiences in life, whether good, bad or seemingly irrelevant, can be of some use to us in terms of knowledge, decision-making and ability, etc.
In terms of study courses, there seems at first glance to be little connection between H&S and the applied geography & geology course I did at college many years ago. However, in retrospect, there were some aspects of the course, albeit small ones, which did have a link. For example, I saw and held sample pieces of mined asbestos including crocidolite which were passed round during geology practicals. Also, in connection with landslides and hydro-geology, we were encouraged to read the Report of the Inquiry into the Aberfan Disaster in which a colliery waste tip slid down a hillside and killed 116 children and 28 adults when it engulfed a primary school in 1966. One of the things which astounded me in the report (it's worth reading) was that NCB mechanical engineers had long been in charge of waste tipping operations. As a result they were wholly outwith their sphere of competence and hadn't grasped the potential dangers of tipping waste on hillsides and especially over springs emanating from them. Furthermore, nobody in the NCB had learned from the hillside tip slides which had occurred before Aberfan, partly because they were in locations where little damage or harm had resulted. I think the report also touched on the NCB's organisation and arrangements for safety at the time, and had numerous references to NCB's then chairman Alfred Robens. Later he became better known in H&S circles as the head of the group which produced for Parliament what proved to be the seismic report of 1972 about H&S standards and enforcement within the UK !
While thinking about getting a job near the end of my course I wrote to the Mines Inspectorate to ask if it had any openings for new inspectors. The reply was yes but added that applicants should have a certificate plus at least umpteen years of experience as a mine manager or similar! This promptly ended my naive aspiration about the Mines Inspectorate, and in retrospect was just as well considering the massive decline of the UK coal mining industry which occurred during the following two decades.
Also, during 1974 one of my fellow geology students who hailed from Lincolnshire was visibly upset after a major explosion at a chemical plant at a place called Flixborough. She knew one or possibly two of the men who had been killed in the explosion. For the rest of us this fact altered our original perception of the explosion as simply another disaster in the news. Furthermore, the news reports which continued long after the explosion kept mentioning an investigation by HM Factory Inspectorate and that it was about to become part of an impending new government organisation known as the Health & Safety Executive (HSE). At the time I never envisaged that within 3 years my first permanent job would be as an inspector with the HSE.
To conclude this post with a nod to the original subject of this thread I didn't go to either of the ceremonies I could have attended, so have no proper idea about the weight and rigidity, etc., of mortar boards. I avoided spending what was then precious money on hiring academic dress for them. Furthermore, friends told me that I spared myself from spending hours having to sit and applaud countless others being given scrolls at the ceremonies! :-)
