I witnessed my grandparents' old age, and it was very beautiful. Surrounded by kids, grandkids, and great grandkids was a beauty to behold. I loved to spend time with my grandpa because of the stories he shared, and he loved us around too, because he would get a lot of laughs. It's so beautiful, however, for another family that are so busy and dispersed around the world, getting professional care will help their old people more. At least, they will be certain that they will get the care they deserve as long as they (the kids) can pay for it.
Our realities are different, so the best is just make sure that our old people do not suffer.
