Daredevil Dies in YouTube Swing Stunt An amateur daredevil from Utah died while attempting to duplicate a popular YouTube stunt involving a rope swing under a massive desert arch. Kyle Lee Stocking, 22, was attempting on Sunday to use climbing ropes to jump off a cliff and swing beneath the 110-foot Corona arch near Moab, Utah, police said today. Stocking made the rope too long, and when he jumped, he ended up diving into the ground and the impact killed him, according to Lt. Kim Neal of the Grand County Sheriff's Department. Neal said that many climbers have been attempting the swing beneath the arch recently. A video called "World's Largest Rope Swing" that shows a group of climbers flying under the arch on a rope may have inspired copycat attempts, Neal said. The video has received more than 17 million views on YouTube. The Sunday accident was the latest in a string in which daredevils have been injured or killed doing stunts that are made popular in YouTube videos. Last September, 15-year-old David Nuno of Chula Vista, Calif., died trying to pass out on purpose in the "choking game," after seeing videos of teens passing out to achieve a "high." Just like in the video, Nuno was standing before he lost consciousness. When he fell forward, he crashed onto an empty drinking glass and broke it with his collarbone, allowing the shard to slice through his interior and exterior jugular arteries. Other teens and adults have imitated videos by jumping off moving vehicles, eating a tablespoon of cinnamon, burning their skin with ice and salt, and participating in amateur "ultimate fighting." Dejah Reed, a freshman at Huron High School in Ann Arbor, Mich., spent four days in the hospital with an infection and a collapsed right lung after she ingested cinnamon in March, 2012, imitating the popular "cinammon challenge" videos. Emergency rooms are seeing more and more teens with injuries that result from emulating things they see on YouTube videos, according to experts. Dr. Thomas Abramo, the chief of pediatric emergency medicine at Vanderbilt University Medical Center, said he sees all of it in his ER. Although teens have acted on risky behavior fads throughout his 30-year career, he said he's seeing trends catch on faster than ever before, and he thinks it's because of YouTube and social media. "If you get one kid doing it, you tend to see more kids doing it," said Abramo, who said two of his patients have died playing the choking game. The spread of the event is definitely faster. One challenge that scares Abramo involves being hit on the head with a bench or a folding chair to "see if you can take it," he said. A lot of the time, they can't. "Fractures, concussions, lacerations," Abramo said. Just the things you would think would happen. "Once you see some of these videos, you go, 'Oh my God,'" the doctor said. The "Darwin award" videos, which involve varying dangerous challenges, are the worst he's seen. Survival of the stupidest. I can't believe it happens. It defies logic," Abramo said. YouTube's guidelines prohibit content that encourages dangerous behavior, but 72 hours of new video are uploaded each minute, according to YouTube statistics, making it difficult to prevent dangerous content being posted. "We count on our users to flag content they believe violates the rules," a YouTube spokesman said. We review flagged videos around the clock and remove all those that violate our policies. Dr. Alan Hilfer, a child psychologist at Maimonides Medical Center, said he thinks the existing videos validate risky behavior for teens and give them a way to get notoriety if they post a video. He said he hears a lot about YouTube's amateur ultimate fighting videos, which show teen fights with are no rules -- just bare knuckles. "A kid showed me his video of that, and it was appalling," he said. These kids were beating each other to a pulp, and kids were standing around and cheering until somebody gave up. Hilfer, who has worked as a child psychologist for four decades, said videos also validate anorexia and cutting by making them seem normal. "When I first came into the field, nobody cut," he said. However, Dr. Carol Bernstein, a psychiatry professor at New York University's Langone Medical Center, said she doesn't think YouTube alone is to blame for teens engaging in challenges that could seriously injure them because many factors are involved. She said other environmental factors, physiology, and temperament contribute to a child's decision to emulate a video. "Stress here should be on knowing our children, watching behaviors and having conversations with them," Bernstein said. There's no substitute for parents and teachers who are engaging with their kids in general. She said if parents discover their child is hurting himself or herself in any way, they should have a conversation with that child. If necessary, she said parents should reach out to a pediatrician to see if he or she should be evaluated by a child psychologist. "The message here if for parents to not be afraid to have conversations with their children," she said. We need to do that.
