I think it was Gologit that said something like "You aren't a logger until you hear one of your bones snap" Hmmmm....in the course of duty I have broke my right collarbone twice, in the same place, cracked three ribs, had maybe three fingers broken. That is just the bones that broke, my knees are shot, my shoulder bones on the right wander around some, add in a few dozen other moderate to minor injuries. I have never been cut by a moving chain, but I have had stitches from most of the pointy things on chainsaws.
When I turned 50, a whole lot of those chickens came to roost, time for a rebuild.
While some things happen faster than you can move, some of those can be avoided, some can't. The harder you push it, the sooner you will be hurt, it's a given. Such is (was) life in high production logging, it's a rare day that you don't shed blood.
