　　Every Sunday from November through April, a group of men and women run shouting into the freezing waters of the Atlantic ocean off the coast of New York city. Are they crazy? Maybe. Do they have a great time? Definitely.

　　The Coney Island Polar Bear club was 16 in 1903 by Bernarr Mactadden. He believed that a regular dip in cold water had big health 17 .He proclaimed this theory while in the 18 water as onlookers were shocked. Now every Sunday, men and women still flock to the polar Bear club’s 19 outings as a way to “chill” water temperatures 20 from about 60°F to about 33°F. Add to the wind chill factor, and you will have one frosty 21!

　　Swimming with the Coney Island polar Bear club takes some 22. First, you should go to the clinic to have a check by your 23 before swimming in cold water to make sure you’re in 24 physical health. Next, you’ll need a bathing suit and a warm towel. Most members 25 wear special boots that protect their 26 from rocks and other sharp objects on the beach. The boots also help keep their feet 27 in the freezing water.

　　Once you’re ready to go, it’s just a matter of gathering the 28 to make that big leap. Plenty of prepare end up at the water’s edge and 29 cowardly at the last second. If you’re sure you want the Polar Bear 30, you might want to bring a friend who won’t let you leave until you’re taken the jump into the freezing water!

From massive beasts to tiny creepy-crawlies, these creatures have a reputation for being killers—and they are! But their death tolls are not nearly as high as you might think.

　　Sharks

　　For decades, Hollywood blockbusters have portrayed sharks as toothy killing machines with a taste for human flesh. But shark attacks, and fatalities, in particular, are probably much rarer than you think. Some species of sharks, like the whale shark and the basking shark, don’t pose a threat to humans at all, despite looking pretty menacing. Even the species of sharks responsible for the most attacks on humans (bull sharks, tiger sharks, and white sharks) don’t actively seek to eat humans. They prefer the taste of fish and seals and can actually find humans difficult to digest. On average, sharks are responsible for six human deaths a year. That’s notably fewer than some much less maligned creatures, including hippopotamuses, elephants, and cows (yes, cows)! Find out some more animals that you didn’t realize were more dangerous than sharks.

　　Bears

　　“Lions and tigers and bears, oh my!” While the Cowardly Lion is the gentle giant who befriends Dorothy’s gang in The Wizard of Oz, bears are actually the least deadly of the three predators from this famous scene. It can be challenging to get a precise estimate of how many humans lions and tigers kill per year, but it’s always quite a bit higher than bears’ statistics. Estimates of human deaths by both lions and tigers can range from 50 to 100, highest in countries such as Tanzania and India. Combined, brown and black bears only kill an average of one to three humans a year in their native United States and Canada.

　　Spiders

　　Don’t get us wrong—black widow spiders are deadly. But many types of spiders—even some of the biggest and scariest-looking ones—don’t often bite and certainly can’t kill you. Spider bites cause an average of seven human deaths per year in the United States. That’s fewer than

At a Dal.komm Coffee shop in Seoul, a robot takes orders from you through a mobile app or a touch screen and then makes fresh coffee. The robot can make up to 14 drinks at a time. Choi Eun Jin thinks the process is fun and easy. The 30-year-old office worker said, "The area is crowded with office workers and local residents during lunchtime. So it's good to have a robot like this ... so you can get your coffee more easily."

　　Coffee is just one of the many industries that use automated services in this technologically forward-thinking nation. Others include restaurants, food stores, banks and manufacturers. The development comes as many Koreans, especially the young, are struggling to find work.

　　South Korea has been an early adopter of automation. It had the highest percentage of robots to human workers in the world in 2017. The International Federation of Robotics say South Korea has 710 robots for every 10,000 manufacturing workers. The international average is 85 robots per 10,000 employees.

　　Even with the job losses, South Korea's businesses are replacing employees with automation and young people are welcoming the change. Lee Sang Jin said, "Currently, Millennials — those who were born after 1980 — are prime consumers. This generation tends to not like meeting other people, so they favor ... technology that enables people to minimize face-to-face interactions..." At the recently opened LAB101 store, customers can open the door with their credit cards 24 hours a day. Once inside, they can try on jeans and pay for the purchase without having to deal with an employee.

　　Back at Dal.komm Coffee, a robot can make about 300 cups a day at the cost of $2 to $3. While some customers like the robot barista, others do not. "Personally I prefer human baristas," said Lee Sang Jin. He added that the robot cannot make custom drinks as well as a human. "I like weak coffee, but the robot is unable to control the strength of the coffee well," Lee sa

At a Dal.komm Coffee shop in Seoul, a robot takes orders from you through a mobile app or a touch screen and then makes fresh coffee. The robot can make up to 14 drinks at a time. Choi Eun Jin thinks the process is fun and easy. The 30-year-old office worker said, "The area is crowded with office workers and local residents during lunchtime. So it's good to have a robot like this ... so you can get your coffee more easily."

　　Coffee is just one of the many industries that use automated services in this technologically forward-thinking nation. Others include restaurants, food stores, banks and manufacturers. The development comes as many Koreans, especially the young, are struggling to find work.

Cruz Genet, 11, and Anthony Skopick, 10, couldn’t agree. Were the birds on the ice ducks or geese? There was only one way to find out. So on a chilly January evening, the two friends went to the frozen pond near their house in Frankfort, Illinois, to get a better look. First they tossed a rock onto the ice to test it . Cruz told NBC 5 Chicago ,“ Then we stepped on it” Convinced the ice would hold their weight, Anthony took a few steps, then....FooMP. He crashed through the seemingly frozen surface.” There was no sound, no sound, no crack,” he told NBC 5 Chicago.” I just fell through instantly.”

　　Cruz rushed to help his panicked friend.--the pond swallowed him too. Gruz managed to lift himself out of the freezing cold water and onto a more solid section. He then cautiously worked his way toward Anthony. But the ice didn’t hold, and he fell in again. This time he couldn’t get out. The boys were up to their necks in icy water and quickly losing feeling in their limbs. Any chance of their feeling themselves was slipping away. Gruz was sure he was going to die.

　　Anthony’s older sister had seen the boys fall through the ice and started screaming for help.

　　John Lavin, a neighbor driving nearby buoy, kicked off his shoes, and ran into the freezing water, Lavin made his way to Gruz and Anthony and hauled them back to land .They were taken to the hospital, where doctors, discovered that their five-minute stay in the water had lowered their body temperature nearly ten degrees.

　　Fortunately, the boys have fully recovered, though they are still a little awe-struck by their fearless neighbor. “Just to think,” says Gruz, “if he wasn’t there, I could have died.”

What led the two boys to the frozen pond?
