A student at Equestrian Trails Elementary School in Wellington, Florida nearly died last week from a freak accident. If it weren't for the quick thinking of his teachers, he likely would have.Annalisa Moradi and her 8-year-old Kolston are counting their blessings."Without them, this story would have been different,” Moradi said.Kolston, a third-grader, nearly died last Wednesday, all because of a wooden pencil."He's a hockey player, he's a lacrosse player. I think and worry all day long about what's going to happen to him and little did I know that it would be a pencil that would ultimately almost end his life,” Moradi said.Kolston had just sharpened the pencil and placed it point up in his backpack sleeve."When I went to go sit down, it stabbed me in my artery," Kolston said.The brachial artery in his arm was impaled. Half the pencil sank into the skin just above his armpit."I didn't really feel anything,” he said.And that’s why Kolston accidentally pulled the pencil out when he stood up. With blood pouring everywhere, Kolston immediately ran and told his nearest teachers."We plan for so much with our schools, our crisis response teams. Our first aid training and everything but this was just one of those things that wouldn't be written on a piece of paper to prepare for,” said Elizabeth Richards, one of the teachers who helped Kolston. "It was one one of those freak accidents, we knew that he needed medical attention immediately."Richards actually studied in nursing school before becoming a teacher. That background expertise took over, despite being surrounded by countless children walking around the hallways during class dismissal."We laid him down on the floor, applied continuous pressure to the point,” she said. "Other instincts take over and everything else around us didn't seem to matter. Kolston really is the true hero here. He came right out and got an adult."Teacher Mandi Kapopoulos used her own shirt sleeve create a tourniquet."I pulled my arm out of the sleeve and wrapped it around his arm where it was bleeding,” Kapopoulos said. "He was brave. He wasn't crying. He wasn't screaming."It took paramedics 20 minutes to arrive but the teachers stayed with Kolston the entire time, applying pressure to the wound."As a teacher and as a mother, I would want the same thing for my children, to put the kids first and to try in any situation like that to do what we need to do quickly and calmly," Kapopoulos said.Since the injury happened toward the end of school, Annalisa Moradi was actually at the front of the school waiting to pick her son up. Teachers informed her of what happened and helped take care of the other children while waiting for the ambulance."He was covered in blood and I knew if was obviously very serious," Moradi said. “Without the teachers and the principal, this story would have been different."It wasn’t until Moradi was en route that paramedics told her just how serious the injury was."When we were taking the ride in the ambulance, they told me if these teachers didn't place a tourniquet on his arm, we would have lost him," she said.With two staples in his arm, Kolston went back to school the very next day.His teachers hope this experience can be a lesson for other parents."As a mother of two children myself, knowing how precious life is -- our thanks and gratitude comes everyday when we watch Kolston walk through these hallways," Richards said.Moradi will make sure her son is more careful next time he packs his backpack."Even if you're in a hurry, there's a place for your pencil -- your pencil box! Slow down, take the time to put it in there," she said. "Just be aware of what's going on around you."Medical experts suggest that if you get impaled or stabbed, it’s best to leave the object in until paramedics arrive so that blood can’t escape the wound.As for Kolston, he did not need to get a blood transfusion, thanks to the teachers helping to stop the bleeding. His staples in his arm should be removed in a few days. 4091

A second report in as many days is predicting an “extremely active” hurricane season.The National Oceanic and Atmospheric Administration released their annual August update for the Atlantic hurricane season Thursday. They are predicting 19 to 25 named storms, where 7 to 11 of them become hurricanes and 3 to 6 of those become major hurricanes with winds of 111mph or greater.Hurricane season ends November 30.There have already been nine named storms in 2020, the earliest that has happened since historical records began. Hurricane Isaias was also the fifth storm of the season to make landfall. It’s the fastest we’ve gotten to five land-falling storms since the old record set back in 1916.Historically, according to NOAA’s Climate Prediction Center, only two named storms form on average by early August and the ninth storm typically does not form until October.“This is one of the most active seasonal forecasts that NOAA has produced in its 22-year history of hurricane outlooks,” said U.S. Secretary of Commerce Wilbur Ross. “We encourage all Americans to do their part by getting prepared, remaining vigilant, and being ready to take action when necessary.”On Wednesday, Colorado State University’s Tropical Weather and Climate Research Center released their final predictions for the 2020 hurricane season. They believe there will be roughly 24 named storms, and 12 hurricanes.“The primary reason why we’re forecasting such an active season isn’t as much the storm activity that we’ve already had, but the large-scale conditions we’ve observed during July and what we expect to see during the peak of the season,” said Dr. Phil Klotzbach, from Colorado State University.NOAA says current oceanic and atmospheric conditions are making 2020 an active storm year, including warmer-than-average sea surface temperatures, reduced vertical wind shear, weaker tropical Atlantic trade winds and an enhanced African monsoon.Both groups say their predictions are for overall seasonal activity and do not predict landfall. Whether or not a storm comes on shore is determined by short-term weather patterns in a certain area at the time the storm forms. 2159

A new study about video gamers pretty much shatters the stereotype many people have about them.Researchers at the Queensland University of Technology in Australia conducted what they say is the first study on body mass index from a worldwide sample of e-sports players. What they found surprised even them.“When we went into the study, we were kind of expecting that the gamers would have a much higher BMI than the general population, but what we found was the complete opposite. We found that players tended to have up to 21% more likelihood of being a normal weight,” said lead researcher Michael Trotter.The study included hundreds of participants from 65 countries. It showed gamers were between 9% and 21% more likely to be a healthy weight. Players also drank less and smoked less than the general population.Trotter started the university's e-sports program before he started studying for his PhD. He says he was surprised that serious players focused on their health almost as much as their playing. He says players requested a personal trainer, a dietician, and a sports psychologist.The study also found the healthier players were the better players.“We found that the players who were in the top 10% of all players and we measured up to 2.5 thousand players, it wasn't a small study. We found the top 10% of all players were exercising significantly more than their lower ranked counterparts,” said Trotter.Trotter says the growth of e-sports is huge and future programs will need to look at this study and realize they must focus on the health of players.He also says future research will need to be done on the overall health of e-sports players, such as muscle mass and bone density. 1706

A pro-growth group's sweeping victory this week could smooth the road for more dense housing in San Diego's uptown neighborhoods.The group, Rise Up Town, won all seven open seats on the city's Uptown Planning Group. The all-volunteer board makes official recommendations to the City Council on proposals in Hillcrest, Bankers Hill, Mission Hills and parts of University Heights. Rise Up Town campaigned on "taller, well designed buildings," with support for affordable development, faster approval, and more walkable and bikeable neighborhoods, with lower speed traffic. It also said the current board members weren't doing enough to support growth in a time that San Diego needs it. "We thought that we could address the problems that we saw in terms of housing affordability, in terms of bike and pedestrian infrastructure within the community," said Clint Daniels, one of the newly elected members. "We got together, we were passionate about it, and we thought those passionate ideas that we could serve the community well."About 500 people voted in the election, held Tuesday before the Uptown Planning Group's meeting. The vote unseated three incumbents, including board chair Leo Wilson. Mat Wahlstrom, who lost his bid for re-election, said he's concerned the new members could serve as a rubber stamp for developers. "None of us have said anything against appropriate density," he said. "We definitely don't want to put all of uptown under saran wrap."There are 17 members on the Uptown Planning Group. Another seven seats are up for re-election next year. 1573
