Reality check: The ocean isn't as tranquil and calm as we sometimes like to picture it. That's why we teamed up with The Shallows — the new shark-attack movie starring Blake Lively, hitting theaters June 24 — to get a taste of what it's like to fight to survive unexpected situations.Do you know what to do if you're swept out into the ocean? Neither did we! But we sent ever-adventurous R29er Lucie Fink into the water to learn the ins and outs of ocean safety and whether she has what it takes to be a lifeguard. Follow along as Lucie demonstrates what the pros do to keep beachgoers safe and how they act fast in case of emergency. If nothing else, let this be a reminder to stay calm. And maybe to not swim or surf alone off remote beaches.
