Ever wonder what your funeral would be like? Some South Koreans aren’t waiting to find out. The Hyowon Healing Center in Seoul runs a free program where people act out a mock funeral to better appreciate life. After an instructional lecture, participants are led into a dimly lit hall, where they sit beside caskets and write their last testaments. Then they put on burial shrouds and lie in coffins in utter darkness for 10 minutes–which can feel like an eternity. Jeong Yong-mun, the director of the program, says 15,000 people have gone through mock funerals since 2012, and businesses often send employees there as part of a motivational program. Most participants say they feel strangely refreshed afterward, gaining a new perspective on life. At the end of the two-and-a-half-hour session, Mr. Jeong tells the participants: “Now you have shed your old self. You are reborn to have a fresh start!”
