From Kristie Harper - Regeneration Nation:

I've just finished a "Durable Power of Attorney" form that our family is using to ensure we don't have medical tyranny foisted upon us in the case of an emergency at this time. I went over a lot of info figuring out how to insert a clause that doesn't leave the decision of whether one is "incapacitated" or not, just in the hands of the attending physician (since their discretion and incentivizing is largely the problem at this time.)  https://rnation.us/2022/01/17/ensure-your-medical-will-be-respected/
