On the episode of MBC weekend drama "Golden Rainbow" Kim Chun Won (played by Cha Ye Ryeon) went to the CEO of Golden Mountains Kang Jung Shim (played by Park Won Sook) and asked many questions.

On this day, Kim Chun Won asked questioned like, "I'm trying to compare the sales with the past month. The sales is something that I was told you memorize monthly. What is left and right ranges" as he tried to revive Kang Jung Shim's memory.

Kim Chun Won saw that Kang Jung Shim couldn't answer correctly and assumed that she had Alzheimers. Kim Chun Won said, "It's most likely Alzheimer's. Unlike now, no one has been able to catch on."
