On June 26, 2009, the "King of Pop" Michael Jackson passed away at the age of 50 due to a sudden heart attack. Prior to this, he was preparing for a comeback and planning to hold fifty concerts at The O2 Arena in London. Two million tickets were sold out within four hours. The name of the concert was "This Is It".
Although I have never intentionally listened to his songs, I like a movie called "Mr. Lonely".
In the old Japanese song "Atsumori", there is a line: "Life at fifty is like a dream, is there anyone who lives forever?"
