As we get older, we often shave a couple years off our age when we tell our friends, this is done as a joke... BUT in South Korea it will not be a joke, it will really happen. In South Korea, they use a traditional aging system that's different than the rest of the world. Koreans are considered to be one year old when they're born, and a year is added every January 1st. So if you were born today, you'd be one . . . and then TWO in a few weeks, on January 1st. So as of TODAY, this means that a Korean born on December 31st of 2002, would be 19 under the international system, 20 under the counting system, and 21 under the Korean system. Naturally, this has become confusing . . . especially internationally . . . so yesterday, the South Korean parliament passed a law to scrap this methods, and just use the international age for everything.
