Seems like a fundamental social right that we should not have to die alone. I would say it's very similar to not being forgotten. The role of someone who is there with you, for you, and knowing that that person will remember you when you have relinquished this world, even if you are homeless or have no family left is a powerful idea - "a promise". Not only does it provide comfort, but also transformation, as the person who survives you can also learn a valuable lesson on the importance and preciousness of our existence.
Who could best benefit from this kind of experience? How could this kind of commitment to some ones final moments change how we as a society look at death? Should healthcare students all be required to have this kind of experience to understand true compassion for their fellow person? How about those in the police, fire and ambulatory services? How can the process be started early enough so both get to know each other? How best can technology and social tools help to make these final connections? How do we as a society make it acceptable so that one can spend those final moments given our busy daily schedules? What kind of training can healthcare provide to the one keeping "the promise"?
