Johannesburg - Downing a bottle of booze in one go not only is a sign of emotional problems, but also very dangerous. This warning comes from doctors after a YouTube video of an Afrikaans-speaking man, doing just that, surfaced on the internet, Netwerk24 reported. In the video, titled: “Afrikaner man downs bottle of Jägermeister,” the man drinks a big bottle of the digestif in less than 40 seconds. From the video, it can be gleaned that one George Johnson had dared him to down a beer in one go. He then dares a certain “Joyce, Gert and Hoffie” before he downed the whole digestif in one go. It’s not the only video of its kind on the internet. There are several similar videos of Irish men, Americans and Afrikaner men in khaki shirts doing the same with bottles of Jack Daniel’s or brandy. Some of the videos have been viewed more than 5 000 times. In one of the videos, one can hear the man shooting the clip say in the background: “Go Kallie..., Go Kallie...” Some onlookers found it hysterical but for most the comments were negative. There are also those who claim that the bottles don’t have real alcohol because one can’t hear the seal pop. “The bottles are filled with tea or apple juice and then resealed with prestik, said Griffen, author of the website Watkykjy.co.za on Facebook. “I know because one of the people who makes the videos told me.” Charly Nel said on the Facebook page that she’d seen a ranger in Swartwater do it [with real alchocol]. His favourite song was De la Rey. Dr Martin Prins, a gastroenterologist, says a person can absorb a certain quantity of alcohol before it causes major damage. “Your liver is an amazing organ which recovers easily,” he said. “But with something like that, acute or long term damage can cause major problems. Alcohol is toxic for your stomach wall, pancreas and kidneys. It depends on where you’re the hardest hit, especially if there are combinations involved. Dr John-Eduard Bosman, a psychologist who treats people with addictions, says it is disconcerting that people make videos such as that. “Someone like that obviously has a problem,” Bosman said. “People around him are egging him on despite the fact that it’s not a good thing to do. He would never do it on his own, because what will he get out of it?” Bosman says that people do such things to attract attention because they have a psychological need for approval and acknowledgement. Some onlookers find if hysterical, but for most the comment is negative.
