There’s a lot to celebrate when mom or dad reaches a milestone like 80, but even if they’ve reached such a ripe age in perfect health, that doesn’t mean there isn’t cause for caution.

It is not unusual for mom and dad's nest egg to be completely exhausted in just a few short years. So what can one do if the costs of caring for mom are not in the budget?
