I agree, Unfortunately I have been through this before with aging relatives, and have seen it go both ways.
Not just that people die, but many also live to a state where they are unable to make decisions and so those that refuse to plan ahead for that leave a big mess behind for someone else to deal with.
My grandmother didn't want to be kept alive long term fed by tubes and so she put that in her living will while she could still reason..And she wanted to die in her own house not a hospital.
You can never forsee all the issues in advance. Not wanting cpr when in last stages of terminal disease is not the same as cpr because anesthetic went wrong.
Culture of death is on the march.
