What do you need?
I’ve survived for 67 years under sometimes onerous and painful circumstances. Was I “living” only when I was young, strong and in excellent health? And now - in my old age, weakness, and in ill health - am I only surviving but not “living?”

Ever work in pedes onocology? Parents agree to treatments with miniscule survival rates. They do not understand that survival means breathing but not consciousness. They are handed back a slowly dying child, who has been tortured.
Brain cancer? You can survive a long time. Breathing, in pain, dying by the inch. Watching an friend do this now. Not a death I would wish on anyone.
The difference between brain cancer and your example of ill health are not even in the same planetary system.
