No, there are many circumstances in between.
My grandparents both lived in a retirement home for the last few years of their lives. My grandfather died suddenly but my grandmother did not.
My grandmother had a long, gradual decline with dementia. We visited her often and took her out of the retirement home for tea. Her accommodations there were very nice and our family would visit several times per week (grandma had 6 adult children). We would have lunch there and the food was very good. Her dementia meant she could not remember people visiting her but she was not unhappy. She was always happy to see us!
I’m so sorry your grandmother faced miserable circumstances. In Canada we now have legal MAID which I am a supporter of. No one should be forced to live in constant pain without a choice.
In my experience, green/metallic beetles are bad news for gardeners. They lay eggs on your plants and the larva destroy them!
