Meredith (closing voiceover): We like to think we're fearless, eager to explore unknown lands and soak up new experiences, but the fact is, we're always terrified. Maybe the terror is part of the attraction. Some people go to horror movies. We cut things open. Dive into dark water. And at the end of the day, isn't that what you'd rather to hear about? If you've got one drink and one friend and 45 minutes. Slow rides make for boring stories. A little calamity. Now that's worth talking about.
