This is a great topic. I have asked people to ask people close to them what the surviving people would write in the deceased loved one's obituaries, what they would write as an epitaph, and what they would do to recognize their lives. What was discovered was an intrinsic fear that held them back from asking these questions. The people who imagined being dead were concerned about attracting death (we are what we think & talk about), and actually feared what the other people would say. I sensed an underlying fear in those people who hesitated to ask themselves and otehr people questions. I think they were ultimately afraid thatthese people wouldn't know them well enough to do what they would have wanted. Ironically, they didn't have the courage themselves to discuss their desires.
To be wrapped up in fear if to forget to live and redefine meaning in life.
