The New York Times has an article "For the Families of the Dying, Coaching as the Hours Wane". They discuss the details of the hospice movement in the US and how it can help families deal with the impending loss of a loved one. The article also talks about the final hours of a death vigil and the different emotions and dynamics people go through.
But I must admit, this article didn't really appeal to me. It's not something I want to think about right now. But perhaps others will benefit from it.
