Approximately 70 people pledged to "Changing the meaning of life and provide an opportunity to live for others" when they are in a coffin.
Lee Myung-hee (42), a mother of two children, said his experience in a coffin made him realize how much he loved his family and is still too early for him to imagine death.
"It (death) can come to me, because of the age factor. I think it could happen anytime, so I think death is not my business. I think it is better to prepare for my final day in a reasonable manner," he said as quoted by the Telegraph, Friday (07/08/2011).
Kang Kyung-ah, a professor of nursing at the University Sahmyook who held a seminar said the residents are aged 20, 30, and 40 could benefit from being in a coffin and appreciate life because of the high suicide rates in their current age.
