It seems people still think it's ideal to live with elderly members to take care of, but the fact is necessarily not. Since many people live apart from their home town and parents, I personally don't think it's ideal to live together because it could mean either parents or children have to leave places they are familiar with.
Any comment is welcome.
There are lots of retirement communities also. The only grandparent I have left is my father's mother. My mom works in a nursing home. It makes her sad that most of the elderly there aren't visted very often by their family. Both my Grandparents were taken care of by my mom before they died.
