The average time a person spends in a nursing home in Ireland before their death is less than 3 years & only a minority of people spend any time in full time care. Most of us can expect to live at home until we die.
My Grandmother lived exceptionally long, dying at 93, she lived in her own home with family help until 91 before moving to nursing home. She rightly should have gone in her sleep in her own bed at 90 but unfortunately lived a few years too long (her words). She hated the last two years in there and also had to bury her son. I would be a big advocate of assisted dying, I’d happily go in my own home at 90 with all my children happy and healthy rather than dragging it out to the bitter end.
