I was a Red Cross certified instructor when I was a Drill Sgt teaching first-aid and CPR to my soldiers. When I was working for the Dept. of Corrections, we were certified every year. I think I was well trained, I saved a guy at a different job when he got his arm caught in an auger. It ripped the muscles of the side of his forearm, blood was everywhere. I keep him from bleeding out and out of shock. When the EMT's showed, they thought I was one of them. That was a complement to me, that and the fact my guy survived and still has that arm.
I'm also a grandfather. I've patched up a lot of children in much less serious injuries.
