The list is never ending.
And we feel the pinch, living in a core family, where you have to take care of everything. I always loved to live in a joint family, but that never happened. May be when we grow older, there is a slight possibility of living with our kid, helping them ( we could not get it ourselves, but it will be great to pass the help to them), but again who knows !!!
End users will always adopt, human instinct, they will adopt anything, if no other option.
If that is what you want, I hope you can have that in the future. It seems you are very close with your kids, so they might be happy to share a space with you and their new family.
We will see in ten years how things turn out - cards say I am going to live alone :)
Best of luck no matter how it works out!
