Frivolous Friday Nice article Simon, the majority of which I agree with, however I will challenge you on 'passion for safety', firstly in that there are a number of different definitions of the word passion or passionate.
I have got no issue with proclaiming that I have a passion for occupational health and safety. It is what gets me up in the morning, its what I love to do - working with people and understanding organisations to make work better, and giving it 100%.
There is no smell of a rat, there is drive, ambition and enthusiasm - I am confident this removes the need to study finger nails
