💡 If you were to line up all South Koreans in order of age, how old would the person standing in the middle be?

This age, which was barely twenty-nine in 1994, is forty-six these days. Fifty is no longer the upper generation, but the middle generation.

However, those who are fifty actually say this: "Why start something new at this age? It's time to wrap things up." In an era of centenarians, fifty is exactly halftime, so why do we feel like the game is coming to an end?
