Why are we so afraid to talk about our own death? 
Deseret News; by Holly Richardson; 4/21/25 
We are more than comfortable with true-crime and first-person shooter games, but a lot of us do not want to talk about our own mortality. ... ... A whopping 84% of the U.S. population over age 13 ... consumes true crime media, according to Edison Research. It’s the most common topic among top-ranked podcasts. First-person shooter video games are the most popular genre. ... So why is it so hard to talk about our own mortality? Maybe we think we can live forever. ... A survey done last year explored reasons why people are uncomfortable talking about death. The top reason given (37%) was that people did not want to upset others, and the second (34%) was that it is too depressing to think about. About one in five say they’ll “cross that bridge when they come to it” or that they are afraid of dying. Ten percent are afraid that talking about death will somehow make it more likely to happen.
Editor's note: While this data gives insights into communication with patients and families, Advance Directives, and community outreach, I find myself reflecting those of us who have chosen palliative, hospice, and/or grief care as our vocations. Do we protect ourselves from facing our own mortality by staying in "helper" roles, and avoiding our own human vulnerabilities? What conversations have you had with your family? What Advance Directives and legal plans do you have in place (or not)?
