The Sea Devil
At the end of the story, the main character vows to never fish again.
He accidentally caught a devil ray and the rope was stuck around his arm so then he was dragged around and almost killed if it weren't for a dolphin that came to the rescue. So he got pretty lucky. So pretty much he will never go fishing again because he was all ripped up by this thing and I know I probably wound not go in the water again either.
Mountain biking is the more risky thing I do because there a possibility I could fall or get attacked by a bear and that would be bad. So yeah, I would never go mountain biking again if that happened.
