Threshold of understanding...

Actually, every maintenance engineer with >20 yrs experience knows it: industrial accidents are not accidental. Or- at least , very many of them are not. Failures , malfunctions and serious accidents do happen often in apparently pre-arranged way: during holidays, around some internal or external company's feud , associated with some competitive commercial projects , etc, etc...

They defy statistic, reliability figures ,maintenance routines and other man-made rules.

And many remain without visible or explicable causes - unusually early material fatigue, unexpected sealing malfunction, chaotic pressure surge , nearby lightning ... all these reasons and each of them separately would be quite a good explanation in itself , but they can never meet one criterion - timely coincidence with some other events , which would otherwise suggest human origin.

Do not even try to reason with younger guys - they have ready explanation for everything, freshly from university lectures.Those who like You - will keep their opinion on Your personal health to themselves; the others would spread it...

Status quo is certainly easier to be maintained , as those with >20 yrs ( and some think slowly or have bad memory, so the median figure is closer to 25 yrs) go into happy retirement not much time thereafter.

But is it advisable to be maintained....?
