This subject is very dear to me así am the primary caregiver for my beloved Grandmother who is currently 103, but in great health overall. But she recently came do with pneumonia which was frightening. It put a lot into perspective including talks with Hospice.
I believe this service is invaluable to families and definitely should be considered in such difficult and emotional times.
I don't what your faith is, but my faith and experience compels me to say, seek spiritual guidance and pray for strength, peace and direction... I believe there are very few here my age or older except yourself. At middle age, life becomes more about "time" and mentoring others. I am confident you will make the best decision for your loved ones.
