<human>: I am not planning on having children any time soon, if at all in my lifetime.  I've got a great-grandmother who's over 100 and won't die.  I've got a grandmother in relatively poor health.  And a grandfather in decent health.  They all live alone.  They all had at least 4 kids.  They all need someone to check on them relatively frequently.  They all have money. What bothers me is that I can't think of a single friend of mine with a grandparent in a similar position who's parents aren't taking care of that parent in some way. I guess you could argue that having money would mean that you would be able to provide for your care in your old age, but not all of us can rely on that. Social services are pretty lacking for the elderly or poor.

Can you provide a brief overview of the text?
<bot>: Who exactly is going to take care of us when we get old if we don't have kids and are not wealthy?
