"Through the Tunnel" Comprehension Paragraph

I dont think the story is convincing that Jerry takes such a risk like he did in the story and still suvived. I think that if he really attempted that dive in real life he wouldnt probally survived. I think he survived that dive because its only a story,and if Jerry happend to die during that risky dive then the story wouldnt have a continuation to the story to the story and the story would end.
