hey Kev you are so right, many years ago when i was in my twenties i worked for a very large shop fitting company around the saw mill you would not believe the older experienced men that had fingers and thumbs missing and yes these men worked around the biggest blades you could imagine and yet they still had bad injuries and yes they over time became complacent some of the men would say they got so used to the humming of the big saws they almost became unaware of the dangers until they got bit, i know this is a bit off topic but you cannot stress the importance of safety at work , i know a young joiner who took the guard of the thicknesser at his dads joinery shop and almost lost his hand trying to rush a job and after a lot of grafts he sure shows the machinery a lot more respect , and yes his dad went nuts when he saw the hand and the guard removed well almost the hand.
