The cost of a piece of metal in your eye.

I feel like I used up a lot of luck in my younger days, guilty of every unsafe behavior there is, never getting any serious injury except for abrasive specks from a belt sander in the eye. Since I've survived into middle age without getting squashed under a car, eyesight intact, all my fingers and toes there and still working, and most of my hearing I try and be damn careful these days.
For quite a few years during my working career I was operating machines like band saws, lathes and milling machines, which can easily remove body parts if you don't pay attention. I did, in fact, have a close encounter with the band saw but, once again I was lucky and only got a small scar.

Something I witnessed, however, taught me tremendous respect for the band saw. I had a friend who was a meatcutter. One time I had him cut a steak special for me. He went and got a side of beef out of the meat locker and set it on the band saw, turned it on and proceeded to RAM the meat into the saw. It seemed like it only took the saw a split-second to cut through the meat, bone and all. I stood there stunned, thinking, holy s%&t! that could have been my hand gone that quick. After watching my friend work I was amazed that he still had all his fingers, although they were pretty heavily scarred up, so he had obviously had some close encounters too and had been lucky.
