If you want to be taken care when you're really old, your best bet is to save money to pay for that service. Kids are no guarantee.
I just went through this with my mom. She needed 24/7 care that I couldn't give her. Thank God we had the resources to get her into a "good" place. It was $5k/mo for 300 sq ft in a very low cost of living metro.
And just because the building is new and the grounds are beautiful does not mean you get better care.
