I cannot believe how strong that man is. What did he wrap his arm with? It would be interesting to get the details. Do you know how big the alligator was? If the alligator was small, maybe the injury was not severe. I cannot imagine that the alligator was fully grown. It seems impossible that a man could physically free himself from the jaws of such a large creature. I hope that you can include more details because it will change my perspective of the story.
