Eleven people have died so far in 2019 while climbing Mount Everest, a behemoth of a mountain that towers 29, 029 feet above sea level. This is more than twice the number of people who died climbing Everest in 2018, which saw only five deaths that season.But it's not the number of deaths that some may find shocking — it's the reasons behind them. Only two of this season's Mount Everest deaths can be attributed to falls.So what's killing climbers ascending the mountain? It's primarily exhaustion and altitude sickness, and something called "the death zone."Seasoned climbers call any part of the mountain above 26,000 feet "the death zone" because there is only so long a human can survive at that elevation due to lack of oxygen. "Even when using bottled oxygen, supplemental oxygen, there's only a very few number of hours that we can actually survive up there before our bodies start to shut down," mountain guide Adrian Ballinger told CNN. And, unfortunately, the wait at the summit of Mount Everest plays a role in these deaths because the longer someone is at that altitude, the more severe they feel the effects from lack of oxygen and exhaustion. During the week beginning May 20, crowds of climbers became stuck in a queue to the summit. When this happens, climbers aren't eating, drinking or sleeping and continue to use up vital oxygen, which can lead to death.British climber Robin Haynes Fisher was one of those who had warned of the dangers of overcrowding."With a single route to the summit, delays caused by overcrowding could prove fatal so I am hopeful my decision to go for the 25th will mean fewer people. Unless of course everyone else plays the same waiting game," he wrote in a captioned Instagram post on May 19.He died after suffering from what appeared to be altitude sickness at 28,215 feet, while returning from the summit on Saturday.Altitude sickness occurs when people are at high elevations for an extended period of time. It can happen anywhere that's 8,000 feet above sea level or more. There are three types of altitude sickness. From least to most severe, they are: acute mountain sickness, high-altitude pulmonary edema (HAPE) and high-altitude cerebral edema (HACE). The symptoms for all three types are similar (headache, fatigue, dizziness, nausea, vomiting, shortness of breath), but HAPE is accompanied by a buildup of fluid in the lungs and HACE, the most severe type of altitude sickness, occurs when there's a buildup of fluid in the brain.So how can climbers avoid the same deadly fate as the 11 who died? Simply put — be careful. Acclimate as slowly as you can to increased elevations, drinks tons of water, rest and immediately start descending if you feel symptoms of altitude sickness.CNN contributed to this story. 2782

Despite expanded netting at Minute Maid Park in Houston, a foul ball that was lined off the bat of Chicago Cubs hitter Albert Almora struck a toddler sitting down the left field line on Wednesday. Almora, a 25-year-old Florida native who is in his fourth year as a Cubs outfielder, dropped to his knees in grief as soon as the ball left his bat. The child was carried away to receive medical attention. According to MLB.com reporter Brian McTaggart, Almora went to a security guard to find out the child's condition. He then shared a hug with the guard and multiple teammates. Sportstalk 790 in Houston reported that the child is expected to be okay. 663

DJ Kashief Hamilton says he was playing music on a cruise ship dock at St. Thomas in the US Virgin Islands when he heard a loud scream. The DJ stopped the party.He says he saw people running, including friend Randolph Donovan, with whom he works as an entertainer for visitors to the island.The 34-year-old Donovan jumped about 10 feet down off the dock into the ocean. A young woman in a wheelchair was sinking."I got her out of her wheelchair," Donovan told CNN. Someone on the dock threw down a life preserver, he said.Then Hamilton, 33, says he jumped in to help his friend, who was holding up the young woman, kicking furiously to keep the two of them afloat. "I can't go no more," Donovan told Hamilton.Hamilton said the water was about 35 or 40 feet deep where they jumped in, making it more than deep enough for the woman weighted down by her wheelchair to sink.Together with onlookers atop the dock, Hamilton and Donovan pulled the young woman back up to safety.They never got her name, but they said one of her family members gave them a big hug."I'm glad the outcome was something positive," Hamilton said. "We would have lost someone who is both a family member and a passenger."They easily could have lost their own lives, too, if a gust of wind had buffeted the waves, moving the massive Carnival Fascination cruise ship parked at the dock. If the ship had shifted a few yards, the three could have been crushed against the dock, Hamilton said.A spokeswoman for Carnival Cruise Line declined to identify the passenger who was rescued, but told CNN, "The guest was seen by our medical team and did not sustain injuries. A complimentary replacement wheelchair has been provided for the duration of the cruise."Strangers now call them heroesHamilton and Donovan said the governor and a legislator applauded their rescue efforts.The two men said US Virgin Islands Gov. Albert Bryan, Jr. called them and told them, "On behalf of the people of the Virgin Islands, I want to say thank you." 2009
