I posted awhile ago about a buddy of mine from work who did almost the same thing. He was cutting rounds from a pile of logs stacked by a log truck. One had a little stub of a branch on it and he swung the saw to the side loosely to cut it off. He misjudged the distance and the tip hit the log. He woke up covered in blood, good thing it was right beside the house so it was a quick trip to the hospital. Bar nailed him right across his face, again glasses saved his eye but cut the heck out of his chin, lip and eye brow. He's pretty stubborn and didn't bother doing exercises or anything. His skin was hanging down because he took bandages off away, the skin over his eye hangs down low and now his eye lid doesn't open anymore. He lost the muscle tone and can't open it. He needs cosmetic surgery but I doubt he will do it.
I pick my battles when I'm in the bush or working wood. I do physical work first when I'm fresh and then as I get tired I do les physical work and use the tractor. Sometimes your head isn't in it and things don't go right and I just call it a day and find something safer to do.
