The good news is that we can now plan in detail for how we want to be cared for at the end of our lives. Since January 1, 2016, it's paid for by Medicare.
So, why not sit down with our medical doctor and have all that put into writing. There's every reason to do that while we are still perceived as mentally competent to make those kinds of decisions.
Geriatric and hospice nurses tell me horror stories. There are those who don't complete those end-of-life directives. That puts them in the hands of the legal system.
Essentially, that system will mandate that life be sustained. That could include feeding you with a tube when all you want to do is die. Or your heart can be continually restarted, even if your brain has been without oxygen for a while.
With there eyes, patients will seem to plead with the hospice nurse to allow them to die. But, legally, that can't happen. Feeding will be maintained.
It's in our self-interest to specify the terms and conditions of how we want to make our exit from this realm of consciousness. And since Medicare covers the cost, there's no longer any excuse for delay.
