I think an educational activity would be to go into an ICU and see the near dead on ventilators, smell the smell, see the stage four wounds
A "scared straight" program for seniors...

All kidding aside, we'd have to send their families with them and have them say "I NEVER WANT TO BE IN THIS CONDITION." I've had so many elderly trauma patients' families go against their advance directives because "Pawpaw wasn't supposed to go like this." Like some awful terminal disease or a big MI would be a better way to die?
I know alot of what I've said sounds callous, but I've walked in their shoes. My family and I had to make the decision to make my mother a DNR when she had terminal CA, and it was one of the most painful and difficult decisions of my life. Now, nearly ten years later, I'm grateful to that kind oncologist for being truthful with us and allowing palliative care to take over. Having been on both sides, I can honestly say that a morphine drip and your family close by is a much more peaceful way to go than with someone thumping on your chest.
