All the guys who taught me the trade of carpentry were missing parts of their bodies. Most could count to eight and a half. Less than safe tools. Cavalier work practice. Machismo. All contributed to the butchery. My worst accident was years ago. Wanted to get a four car garage framed that went with a large remodeling project. It started to rain. I was using a pneumatic framing gun. It pops a three and a quarter inch spike into lumber with a touch of the tip in less than a second. Rain made the boards slippery. I was holding the pieces with one hand and shootng with the other. The gun slipped. Shot a spike into my left thumb. Right at the base where it joins the hand. Disbelief. Lay down the gun. I wasn't scared tilI tried to pull the spike out. Wouldn't budge. Solidly in bone. Grabbed a pair of pliers from my tool belt and finally extracted it. Little blood. Classic puncture wound. Then watched it swell and swell. Now it's rare to see these kind of accidents. Tools are much better designed. Better safety features. The trades learn safe practice from day one. Nowadays hardhats, eye and ear protection, high visibility vests, safety shoes and harnasses are standard on commercial jobs. BTW. I can still count to ten. Twenty if I have to. . .
