I didn't really mean to make people think the only recourse was to euthanize themselves. I really just wanted people to know that this cheerful cultural trope of some mythical "great wealth transfer" might not actually work as promised.

I don't know what is legal anywhere but you can definitely find and fill out forms to let your loved ones know your wishes--like prioritizing palliative care rather than extreme measures to "add longevity."

Once somebody here pointed me to this website (I'm pretty sure this was the one) with very helpful worksheets to start and explain your wishes. I wish you the best of luck. https://caremattersllc.com/wp-content/uploads/2017/09/good-to-go-values-worksheet.pdf
