As a full-time carer to my Mother Who has Alzheimer's for over 2 1/2 years, I asked Mom this question while She's still capable of thinking for Herself. Suppose you had to go into a hospital or a care home at the latter stage of life, and you needed to be fed by tube or needed resuscitation, would you want this?
The answer Mom made Me was absolutely positive, with NO hesitation.
NO..NO WAY, let me go quietyly into the night...when life is gone from me, why bring me back, back to what? More suffering?
I needed to hear this from Mom, as I will see that Her wishes are carried out to the LETTER.
